Flex Power Modules introduces 8:1 non-isolated bus converter

Product ImageFlex Power Modules has launched the BMR320, a non-isolated, unregulated, DC-DC intermediate bus converter with a fixed 8:1 input/output voltage ratio in a compact form-factor.

The product operates over a 40-60 VDC input range, producing a 5 to 7.5 VDC output, ideal for powering point of load converters at lower intermediate bus voltages to optimize system efficiency. The BMR320 is rated at 400 W/60 A at 54 V input and achieves an outstanding power density of 128 W/cm3 (2126 W/in3), measuring just 27 x 18 x 6.4 mm. With efficiency peaking at 97.7%, up to three units can be paralleled for a total load of 1080 W. The parts are designed for top-side cooling to a heatsink with airflow or for liquid cooling via a thermal block, and the relatively flat design of the topside of the converter allows for easy connection via a thermal interface material such as a gap pad.

The unregulated, non-isolated architecture used in the BMR320 reduces the output impedance of the converter when compared to regulated designs, which effectively reflects the input bus capacitance efficiently to the output, enhancing its ability to cope with large load transients with minimal “droop”.

The BMR320 protection features include output current limit and over-voltage, along with over-temperature and input undervoltage. A PMBusTM interface is included for monitoring and control and the part is supported by the Flex Power Designer Tool.

Anders Sellin, Strategic Product Manager at Flex Power Modules comments “The BMR320 intermediate bus converter is designed for optimum system efficiency when used alongside point of load converters and Integrated Power Stages such as our BMR510 and up-coming BMR515. It is a great solution for datacom, cloud computing and AI applications, where power density, efficiency and low cost are critical factors”.

The product will be available in OEM quantities by end of this year.

RECOM’s RPX series in QFN package now meets AEC-Q100 Grade 1 requirements

Product ImageThe successful RECOM RPX QFN-packaged DC/DC converters now have ‘-Q’ variants which meet stringent automotive AEC-Q100 Grade 1 requirements and have been upgraded to include ‘wettable flanks’ for Automated Optical Inspection (AOI). The DC/DCs have an input range up to 36V, and the output can be trimmed from 0.8V to 30V. The RPX-0.5Q variant delivers 0.5A, and the RPX-1.5Q delivers 1.5A, both in a tiny 3 x 5 x 1.6mm leadless, thermally-enhanced QFN package, operating to well over 100°C ambient with derating. This is enabled by state-of-the-art integration and advanced 3D packaging techniques using an over-molded Flip Chip on Leadframe (FCOL) construction to provide lowest package thermal resistance while keeping manufacturing and end-product pricing low.

The RPX series integrates the necessary inductor and requires just external input and output capacitors, scaled for the customer’s application, for full functionality. On/off control and synchronization inputs are provided with a power good output. Soft start along with full short circuit, over-current, over-temperature, and input under-voltage protection is included. Due to the FCOL construction, EMI is low, and fixed-frequency operation makes any required additional filtering easy to implement.

Evaluation modules are available for both products.

 

Matthew Dauterive, DC/DC product manager of RECOM comments; “The success of our RPX range has spurred us on to further qualify them to automotive standards. This gives our customers extra confidence that they can also be used in other application areas such as industrial or ATE, with high reliability”.

 

The RPX0.5Q and RPX-1.5Q series are available through all authorized RECOM distributors or by contacting the manufacturer directly. Samples can be requested via the RECOM website.

TDK offers compact CeraLink® capacitors in EIA 2220 size

Product ImageTDK Corporation has expanded its tried-and-tested range of CeraLink capacitors. Previously, only large, ready-to-fit sizes were available. Now, smaller versions with the classic chip design are included in the portfolio in order to increase the areas of application. The new portfolio starts with the EIA 2220 size, measuring 5.7 x 5 x 1.4 mm, is intended for 500 V, and offers a capacitance of 250 nF with very low parasitic coefficients. The new capacitors with the ordering code B58043* are available with both standard and soft termination. TDK will add further designs and voltage classes in the future.

At room temperature, the ESR at 1 MHz is only 40 mΩ, and the ESL is 3 nH, with the values even lower at higher temperatures. A high current capability of up to 9 ARMS is achieved at 200 kHz and 25 °C ambient temperature. The permissible temperature range lies between -40 °C and +150 °C.

Typical applications use the smaller designs in either snubber or output capacitors. Due to its smaller dimensions, the new CeraLink SMD variant can be placed even closer to fast-switching power semiconductors like IGBT modules, SiC-based or GaN-based semiconductors. Alongside the low ESL values, the lead inductance is kept very low.

TDK offers PCM120T shielded SMT power inductors with saturation currents of up to 80 A

Product ImageTDK Corporation introduces the new PCM120T series of shielded SMT power inductors, optimized for high saturation currents and low DC resistances. The PCM120T product family includes 14 inductance values between 0.4 µH and 10 µH, whereby saturation currents of up to 80 A are reached depending on the L value. Optimal saturation properties are achieved through the use of an iron alloy core. Flat wire windings are used to keep losses as low as possible. This results in low ohmic resistance values (RDC) of 0.72 mΩ (0.4 µH) to 9 mΩ (10 µH). The new inductors have an outstanding EMC performance due to closed housing made of ferrite material without an external gap. They are ideal for automatic solder joint inspection (AOI) and achieve a coplanarity of <0.1 mm due to their lead frame structure. The product’s metal cores provide resistance against high voltage pulses in accordance with ISO7636. The components’ dimensions are 12.7 x 15.8 x 11.5 mm (W x L x H).. The powerful RoHS-compatible inductors are designed for a wide temperature range from -55 °C to +165 °C and are certified according to AEC-Q200.

Typical applications include primary DC/DC converters in automotive applications such as ADAS, power supplies for servers and base stations, and various types of DC/DC converters. The PCM120T components are also ideal for interference suppression, such as electric motors in vehicles.

Powerbox’s 1200W Power Supply has Adjustable ‘Near to Zero’ Output Voltage and Current for Conduction Cooling Applications

Powerbox, one of Europe’s largest power supply companies, and for more than four decades a leading force in optimizing power solutions for demanding applications, has announced the release of the 1200W rated OFI1200A AC/DC power supply for industrial applications. Optimized for conduction cooling, the OFI1200A delivers high performance levels across a baseplate temperature range of -40 to +95 degrees C without the use of a fan. The power supply operates with a wide universal input range from 85 to 305VAC with power factor correction (PFC). Covering a large range of applications, its output voltage and current can be adjusted from near zero to the maximum allowed for each model.

PRBX_OFI1200A

A number of industrial applications require power supplies to operate with limited or no ventilation cooling. In this respect, those operating in harsh environments where electronic equipment is installed in a sealed box, radio communication systems subject to adverse weather conditions, outdoor displays and traffic signaling, and indoor equipment with very strict audible noise restrictions. In addition to environmental requirements, reliability and cost of maintenance are motivating systems designers not to use fans and blowers.

Conduction cooling requires very specific building practices and the PRBX OFI1200A has been designed to guarantee optimal heat transfer from the dissipating components to the baseplate, delivering a high level of performance within an operating temperature of -40 to +95 degree centigrade at baseplate. Depending on the assembly method and the overall cooling conditions, a derating may apply as specified in the technical documentation.

To cover a large range of applications, the OFI1200A operates with a wide universal input range from 85 to 305VAC (Nominal 100 to 277VAC). The unit includes a PFC with a coefficient of 0.98/0.95 (110VAC/230VAC).
The OFI1200A is available in three versions of single output DC voltage, 12V/84A ; 28V/43A and 48V/25A. Using a high efficiency topology, the typical efficiency for the 48V output unit at 230VAC input is an excellent 92%.
Industrial applications such as professional lighting or even low-power electrolyzers require the power supply to deliver constant current, and this must be easily adjustable. Often such equipments are operated in environments requiring the electronics to be enclosed and protected from hazards. This necessitates the power supply to offer an external control to adjust the output voltage and/or current from the maximum allowed to near zero.

To make it possible for customers to precisely adjust the voltage and current to their application, the OFI1200A offers two analog inputs, VTRM and ITRM. Using those functions, the output voltage and current can be adjusted from near zero up to the maximum specified per model. For example, the 28V output can be adjusted from near zero volts up to 33.6V, and the output current from near zero amps up to 43A. The output voltage can also be adjusted using the provided onboard potentiometer. The extended trimming and control function simplifies the utilization of the power supply in constant voltage (CV) or constant current (CC) mode, without adding external circuitry. For applications requiring redundancy or higher power, it is possible to connect up to nine units in parallel, delivering an impressive total power level of up to 9,720W in conduction cooling mode. To maintain the highest level of efficiency when operated in parallel or in redundancy-mode, optional active ORing circuitry deploying high performance FET technology (Option-O) is available on the OFI1200A28 and OFI1200A48.

In its open frame format, the OFI1200A measures 142 x 39 x 260mm (5.59 x 1.54 x 10.36 inches) and weighs 1.2kg max. An optional metal cover is available, adding just 1mm to the height and 200 grams to the weight (Option-N).
Benefiting from a design optimized for conduction cooling, the OFI1200A is suitable for applications requiring a silent power solution such as in a control room. Equally, it is suitable for industrial applications when forced air ventilation is not possible due to environmental constraints.

Cost-efficient SOIC-16 DC/DC range added by RECOM

RECOM adds 1W and 0.5W options to their SOIC-16 family of DC/DC converters

RECOM has extended its range of DC/DC converters in a SOIC-16 package with new versions which offer even better value. The parts feature 5V (4.5-5.5V) inputs and a semi-regulated 5V output rated at either 0.5W (R05C05TE05S) or 1W (R05CTE05S). Line and load regulation figures are specified across the full temperature range, and there is no minimum load requirement, making the parts ideal for applications that have light-load operation modes.

Both parts have a 3kVDC/1 min (basic) insulation rating with greater than 8mm input/output creepage and clearance, and operate from -40°C to 125°C with derating. Isolation capacitance is just 7pF. Protection features include short-circuit, over-current, over temperature, and input undervoltage, making the parts highly suitable for applications that demand a high level of reliability and robustness. EMI levels are also particularly low compared with more expensive competing products.

The SOIC-16 package is just 10.35mm x 7.5mm footprint and 2.5mm profile, perfect for space-constrained designs. The two parts are pin compatible, allowing future upgrades from 0.5W to 1W if necessary. The DC/DCs are also partially pin compatible with the higher specification RECOM R05CT05S, which includes features such as remote on/off and reinforced isolation.

Applications for the two ranges include isolated COM port power supplies, gate drive power, current sensing/smart metering, medical devices, industrial PLC (I/O), and sensors for IoT/IIoT.

“These new DC/DCs are a low-cost alternative when all the features of our higher spec SOIC-16 parts are not needed”, commented Matthew Dauterive, DC/DC product manager of RECOM. “Even so, they still are manufactured with the same automated process with advanced transformer fabrication technology for the highest reliability in critical applications”.

Powerbox Announces 700W Power Supply Optimized for Conduction Cooling Applications

Powerbox, one of Europe’s largest power supply companies, and for more than four decades a leading force in optimizing power solutions for demanding applications, has announced the release of a new 700W power supply for industrial applications, the OFI700A. Optimized for conduction cooling, the OFI700A delivers high performance levels across a baseplate temperature range of -40 to +95 degrees C, without the use of a fan. The power supply operates with a wide universal input range from 85 to 264VAC with power factor correction (PFC) and is available with DC outputs of 12V, 28V (adjustable to 24V) or 48VDC. A 12V auxiliary is also provided.
 
In many industrial applications cooling of the dissipating elements relies on the use of fans and blowers. But there are applications where it is not possible or even allowed to use active ventilation. In harsh environments or in applications where the required reliability level imposes the need to remove all possible risk of failure, fans and blowers are not allowed. A sealed box such as is required for laser-cutting is but one example, but there is also a growing demand for equipment installed in supervisory rooms or even offices that for the comfort and health of the employees, generated noise is simply not allowed or needs to be very much limited.
 
Conduction cooling requires very specific building practices and the PRBX OFI700A has been designed to guarantee optimal heat transfer from the dissipating components to the baseplate, delivering a high level of performances within an operating temperature of -40 to +95 degree centigrade at baseplate. Depending on the assembly method and the overall cooling conditions, a derating may apply as specified in the technical documentation. To cover a wide range of applications, the OFI700A operates with a wide universal input range from 85 to 264VAC. The unit includes a PFC with a coefficient of 0.95/0.92 (110VAC/230VAC). For applications powered by a DC bus e.g., mining equipment, the OFI700A operates from 120 to 350VDC.
 
The OFI700A is available in three versions of single output DC voltage, 12V/58.4A ; 28V/25A and 48V/14.6A. The output voltage can be adjusted using the provided onboard potentiometer. For example, the 28V output can be adjusted from 22.4V to 33.6V, covering the 24V applications. An additional voltage of 12V/0.1A is provided for auxiliary functions. For applications requiring 1+1 redundancy it is possible to connect two units in parallel, adding an external diode to protect the unit. Using a diode for this purpose is a simple solution but it increases power losses which depending on the output current could be as high as 30W. So, to maintain the highest level of efficiency when operated in redundancy-mode, an ‘option O’ OFI700A version is available with active ORing circuitry deploying high performance FET technology. In this version the power losses are minimized to an excellent less than 1.5W.
 
For safety, the OFI700A has an IN/OUT isolation of 3,000VAC and IN/FG of 2,000VAC. Output isolation to FG is 500VAC. The power supply includes over current protection with auto recovery, over voltage and over temperature protection. The OFI700A board includes easy access to auxiliary functions via on board connectors, namely: Remote Control, Output Voltage Sensing, DC-OK, Inverter Operation Mode (IOG) and auxiliary 12V. The OFI700A has endured shock and vibration testing as specified in MIL-STD-810H. In that respect the products have been tested to levels far above normal operating conditions and are specified to sustain a high 20G vibration level during transportation. The OFI700A is certified in accordance with UL62368-1, C-UL (equivalent to CAN/CSA-C22.2 No.62368-1), EN62368-1. The OFI700A series has a full three-year warranty and conforms to the European RoHS, REACH and Low Voltage Directives. The product carries the UL, CE and UKCA marks.

MinDCet drivers and FTEX powertrain solutions enable EV GaN applications

MinDCet, a leading semiconductor house specializing in power and high-voltage IC design, announced the development of the first GaN-driven Dynamic Drive along with FTEX, the renowned specialist in precision motor control systems using gallium nitride (GaN) transistors.

FTEX develops variable DC bus motor drives for EVs which have been shown to play a significant role in increasing range and power of EV powertrains. However, legacy silicon DC-DC converters are too large to be integrated in an EV powertrain, taking up space otherwise used for batteries. Having the possibility to drastically increase the power density of a DC-DC power converter enables multiple architectures not previously commercially viable.

FTEX finds solutions to these problems by implementing novel topologies and gallium nitride transistors to overcome the size and efficiency issues of variable DC bus powertrains. GaN power transistors have multiple key advantages, such as lower On resistance compared to state-of-the-art silicon equivalents and very sharp commutations that enable high-frequency power conversion and ideal waveform generation. Provided they are designed and driven effectively, this technology can drastically reduce the size of DC-DC converters while maintaining ultra-high-efficiency operation.

FTEX is leaning on the high-performance gallium nitride transistors offered by EPC driven to their full potential thanks to the high-performance MinDCet MDC901 drivers. “With its advanced capabilities and flexibility by design, this single driver can achieve high-performance in various applications, either for power conversion or motor control,” said Alexandre Cosneau, CTO of FTEX. “Exclusive features such as charge pumps, 5V to 6V gate drive voltages, and advanced thermal dissipation allow this driver to get the best out of the EPC GaN transistors, for example. Considering the safety of the power conversion system, a shoot-through event, one of the worst failure scenarios that can occur in a half-bridge, can be greatly prevented by MinDCet’s driver, thanks to its numerous fail-safes.”

The gate driver precision and control directly influence the reliability and efficiency of the system. The gate driver controls the behavior of the half-bridge output, known as the switching node. By generating a near perfect waveform at the switching node, harmonics within the magnetic elements are minimized, resulting in very low losses. These harmonics arise from the over-/under-shoots and their subsequent ringing during commutation transitions, where harmonics are simply wasted energy and damage the circuitry over time. “Driving GaN transistors in a robust and reliable way requires a specifically developed gate driver,” explained Jef Thoné, CTO at MinDCet. “You want to maintain a perfect gate voltage control under high slew-rate conditions to ensure a long lifetime for your GaN power stage.”

The combination of EPC GaNs and the MinDCet driver allows FTEX to effectively use its expertise to design and implement high-performance algorithms and control methods to deliver a DC-DC converter with up to three times the power density compared to the existing state-of-the-art. The result is the FTEX Dynamic Drive, a high-performance, ultra-compact, variable DC bus motor drive that has been shown to provide up to 30% more range and power in a commercially viable, cost effective solution.

Power Integrations’ New SCALE-iFlex LT Plug-and-Play Gate Driver Improves EconoDUAL IGBT Module Performance by 20%

Power Integrations (Nasdaq: POWI), the leader in gate-driver technology for medium- and high-voltage inverter applications, today announced its new plug-and-play SCALE-iFlex™ LT dual gate-drivers. The new drivers improve the performance of multiple parallel EconoDUAL modules by 20%, allowing users to eliminate one of every six modules from power inverters and converter stacks. In addition to saving the cost of the driver and module, this reduces control complexity and costs related to modules, wiring, hardware, and heatsinking. SCALE-iFlex LT targets multiple applications in renewable energy generation and storage, and is particularly applicable to offshore wind turbines in the 3 to 5 MW range.

Thorsten Schmidt, product marketing manager at Power Integrations commented: “Dynamic and static current sharing is critical for robust operation of modules arranged in parallel. For the same power output, systems using SCALE-iFlex LT require just five parallel modules whereas competitive approaches need six. This substantial saving of cost and complexity is achieved by guaranteeing less than 20 ns of variance in turn-on and turn-off commands between modules and less than 20 A of variance between modules when conducting the rated 600 A. This allows the modules to operate reliably without current derating, which is obligatory with less advanced driver solutions.”

Up to six EconoDUAL 3, or equivalent, power modules can be paralleled from the same Isolated Master Control (IMC) unit which has a more compact outline than conventional products. The Module Adapted Gate drivers (MAGs), which fit the footprint of the EconoDUAL module, each featuring two SCALE-2 ASICs – one per channel – to optimize symmetrical paralleling, efficiency and protection.

The new SCALE-iFlex LT gate-driver modules reduce switching losses by three to five percent, due to the fast turn-on and turn-off of the SCALE-2 ASIC which features an integrated booster stage. Power Integrations’ Advanced Active Clamping (AAC) protection enables higher DC link voltages to be achieved. A full suite of other protection features, including short-circuit, are provided. Drivers feature reinforced isolation to 1700 V and may be ordered naked or conformally coated.

As well as renewable energy, other applications include power quality, commercial air-conditioning units and medium-voltage drives. The new SCALE-iFlex LT gate drivers are available now. For more information, please visit www.power.com/scale-iflex-lt.

TDK Corporation today announced the development and mass production of the MMZ1608-HE series of high-reliability chip beads for automotive use, compatible with high-durability solder in 150 ºC environments. This series marks the industry’s first* high-reliability chip bead specifically designed for automotive applications associated with engine control modules (ECM), anti-lock brake systems (ABS), electric power steering (EPS), electric and hybrid electric vehicles (EV/EHV), inverters and LED headlights.

In high-temperature automotive environments, such as engine compartments, high-durability solder is increasingly used to prevent solder cracks in the bonds between chip components and the mounting substrate. Since high-durability solders do not stretch easily and impart higher stress compared with conventional solders, they place a large load on chip components and do not meet the reliability requirements of existing chip beads. With improvements to the terminal electrode material and plating process, the MMZ1608-HE series improves the bonding strength between the terminal electrode and plating, making it ideal for use with high-durability solder in 150 ºC environments.

The four products in the series have a rated current max ranging from 200 to 300 at 150 ºC, DC resistance max between 0.15 to 0.5, and impedance from 120-1000, respectively.

TDK will continue to expand its lineup of compact sizes and various impedances to support a wide range of automotive specifications and designs.

TDK announces new miniaturized, common-mode filters for high-temperature automotive applications

TDK Corporation (TSE:6762) today announced the development of its KCZ1210AH series of miniaturized common-mode filters for automotive applications. The series is extremely compact, measuring 1.25 (L) x 1.0 (W) x 0.5 mm (H), which contributes to a smaller footprint on substrate and provides a noise control function for different transmission signal lines for automobiles.

With an increase in advanced driver-assistance systems (ADAS), demands for automotive cameras are rapidly growing. Forward sensing cameras and cameras for around view monitors utilize common-mode filters as anti-noise products. However, as the conventional multilayer common-mode filter operates within a temperature range of -40 and +105℃, it cannot be used for ADAS cameras and was principally used in automotive accessories.

TDK's series uses proprietary materials technology and structural design to achieve a temperature range from -55 to +125℃; it also has a rated current max of 100 and a rated voltage max of 5. By adopting a conductive resin-based electrode, it controls product cracks due to thermal shock and increases durability against mechanical stresses, such as substrate strains.

TDK is working to enhance its inductive devices for ADAS and will expand its line of miniaturized common-mode filters supporting higher-speed differential signals. Mass-production of this series will begin in September 2021.

TDK offers miniaturized, high performance thin-film common-mode filters for mobile devices

TDK Corporation has developed the TCM0403M Series of miniaturized thin-film common-mode filters for mobile devices. The 0403 case size (0.45 x 0.3 x 0.23 mm) is 58 % smaller and 56 % lighter than previous products. With its high common-mode attenuation characteristic, these products reduce intruding noise and improve wireless signal reception sensitivity. The common mode attenuation at 2.4 GHz is 21 dB, and 28 dB at 5.0 GHz, with a maximum permissible current of 50 mA. Mass production started in August 2021.

Due to the growing multifunctionality of wireless devices such as smartphones, wearables and other mobile products, noises generated inside the devices are deteriorating wireless signals. It is critical to prevent the deterioration of signal reception sensitivity and to prevent external noise that has the potential to cause device malfunction; this series addresses those common challenges.

The products are mountable in ultra-small spaces due to their 58 % footprint reduction, which was previously impossible with the existing TCM0605 Series (0.65 x 0.5 mm case size). By improving TDK’s proprietary fine pattern technology and optimizing design, the products feature a common-mode attenuation characteristic that equals existing products and a differential transmission characteristic capable of supporting high-speed signal transmission.

TDK’s wide array of products meets the needs for common filters for high-speed differential signal lines, including for USB, MIPI and HDMI.

KEMET Introduces Next-Generation Supercapacitors for Automotive

KEMET, part of the YAGEO Group and leading global electronic components supplier, announces its new high-performance supercapacitors for automotive electronics, the FMD and FU0H series. These series deliver 1,000 hours at 85°C/85% RH-rated voltage and operational temperature ranging from -40°C to 85°C. The FMD series offers the highest lifetime with up to 4,000 hours. These supercapacitors are qualified to an automotive testing protocol. These capacitors are manufactured in an ISO TS 16949 certified plant and are subjected to PPAP/PSW and change control. They are ideal for automotive applications needing a main power system backup during a power loss, such as ADAS, autonomous vehicles, and central gateway ECUs. Supercapacitors are ideal for maintaining the main power system’s real-time clock or volatile memory when it is removed, such as during a power failure or when the main power system’s battery has been removed for replacement. Additionally, these supercapacitors offer power backup in equipment ranging from IoT devices, smart meters, medical devices, and industrial computing.

Using supercapacitors for automotive electronics enables freedom from the design limits imposed by finite battery lifetimes. The supercapacitor’s benign open-circuit failure mode contrasts with typical short-circuit battery failures that may result in outgassing or ignition. Furthermore, supercapacitors are a cost-effective alternative to small backup batteries. Depending on the type of load and current demand, they can store enough energy to provide backup for durations ranging from a few seconds to several hours.

KEMET’s miniature supercapacitors use a proprietary aqueous electrolyte solution that provides high durability against liquid leakage, vibrations, and thermal shock, thus high reliability in harsh environments. Aqueous electrolytes are highly conductive, have a low environmental impact, and are non-toxic and non-flammable. Unlike a battery, supercapacitors store and release energy quickly through physical adsorption and the ions desorption in the electrolyte between its electrodes. With the supercapacitor’s low internal resistance, these devices can fully charge within a few seconds. In contrast, a secondary battery cell can take from ten minutes to several hours to fully charge. Moreover, there is no theoretical limit to the life cycle, whereas a lithium-ion secondary cell has a finite lifetime of about 500 cycles. They also typically have a greater resistance to moisture absorption than organic compounds, resulting in a longer life with better stability.

According to an Allied Market Research report, the global supercapacitor market generated $3.27 billion in 2019 and is estimated to reach $16.95 billion by 2027, with a CAGR of 23.3% from 2020 to 2027.* An increase in demand for automotive applications, renewable energy systems, and supportive government regulations is boosting the growth of the global supercapacitor market.

A recent Design Example Report (DER-928) describes the use of two PowiGaN-based IC products to achieve 30.3 W/ in3 power density in a 60 W USB PD 3.0 adapter that is up to 93% efficient. The combination of the new InnoSwitch4-CZ zero-voltage-switching flyback switcher IC (with its companion active-clamping ClampZero IC) and the MinE-CAP bulk capacitor miniaturization IC ushers in a new class of ultra-compact mobile device chargers.

The 1.77 in x 1.77 in x 0.63 in design can provide 5 V, 9 V, 15 V or 20 V to the output to support rapid charging of devices from mobile phones to compact laptops. It consumes less than 60 mW no-load power and requires no heatsinks.

InnoSwitch4-CZ devices incorporate a robust PowiGaN-based 750 V primary switch and work with the new ClampZero high-frequency active clamp ICs. The pair provides a steady state switching frequency of up to 140 kHz to minimize transformer size. It maintains very high efficiency across line voltage, system load and with different output voltages.

MinE-CAP ICs drastically reduce the size of high-voltage bulk electrolytic capacitors, resulting in up to 40% adapter size reduction without compromising output ripple, operating efficiency, or requiring redesign of the transformer. MinE-CAP devices work seamlessly with the InnoSwitch family of switcher ICs and require minimal external components.

Power Integrations PowiGaN Solutions Enable Compact Chargers for eBikes and Power Tools

Typical eBike and power tool adapters come in bulky packages, with much of their volume devoted to thick, heavy metal heatsinks that siphon away wasted energy when they are charging. InnoSwitch3-CP offline flyback switcher ICs featuring PowiGaN Technology enable heatsink-free charger designs that are smaller, lighter, have ultra-high efficiency and low no-load consumption. Thanks to PowiGaN, you can slip your charger into your backpack and charge anywhere you can find an outlet.

A new design example report, DER-915, describes a 84 W (42 V / 2 A) adapter with 160-264 VAC high-line input for eBikes and power tools. The low component-count design fits neatly on a 3.2 in x 1.9 in circuit board; that’s about the size of a bank card. It’s greater than 93% efficient and consumes less than 70 mW of no-load power at 230 VAC.

The InnoSwitch3-CP device at the heart of this design incorporates a 750 V PowiGaN switch, primary and secondary controllers, and safety-rated feedback into a single IC. It’s the ideal solution for constant power charging applications up to 100 W.

Power Integration Safeguard Meters from Magnetic Tampering with New LinkSwith-XT2 Design

Utility meters need to work without interruption and often under adverse conditions. From full load to light load, through line surges, or even when being tampered with, meters require rugged and efficient power supplies to deliver power without fail. A new design example report (DER-711) addresses these challenges with a 6.6 W dual-output flyback converter using a LinkSwitch-XT2 offline switcher IC. With a low-RDS (ON), 900 V MOSFET, LinkSwitch-XT2 improves efficiency at full load, maintains efficiency at light load, and resists magnetic tampering.

Meter tampering is often done by placing a strong magnet close to the meter’s power supply to interfere with transformer inductance. LinkSwitch-XT2 features an ON/OFF control that compensates for the primary inductance reduction by increasing operating frequency to maintain output power level. The ON/OFF control enables high efficiency at light load, allowing utility providers to minimize energy consumption during normal meter operation.

No EMI or Thermal Issues

The DER-711 circuit design utilizes the high current limit of LinkSwitch-XT2 to operate at very low frequency, making it capable of withstanding severe magnetic tampering. When operating frequency increases to 60 kHz due to proximity to a magnet, the design wouldn’t incur thermal or electromagnetic interference issues. In the extreme case when a magnet is in physical contact with the transformer, the drop in system efficiency is limited to 4-6%, and IC temperature increases by merely 16°C at full load. The DER-711 board layout places the transformer in the center, maximizing distance from possible external magnetic interference.

A True Universal Design

The LinkSwitch-XT2 IC’s integrated 900 V MOSFET provides valuable safety margin for meters in regions with high and unstable mains voltage. DER-711 has an ultra-wide 85-350 VAC input range and can withstand 6 kV of differential line surge.

Power Integration 600 V Qspeed Diodes Can Replace SiC Parts in Automotive Applications

PI’s newest AEC-Q100 qualified Qspeed diode has the lowest reverse recovery charge (Qrr) of any 600 V silicon diode. Expanding our portfolio of automotive-qualified diodes, the QH12TZ600Q diode offers the same low switching-loss performance as a silicon carbide (SiC) device without the higher price tag.

Automotive on-board charger applications require higher switching frequency to reduce volume and weight. Our QH12TZ600Q diode has a Qrr of just 14 nC at 25 °C – half the Qrr of competing silicon diodes. It improves the efficiency of power factor correction (PFC) stages in the on-board charger while significantly reducing thermals in PFC MOSFETs.

Like our other Qspeed diodes, QH12TZ600Q uses merged PiN and Schottky diode technology to achieve high performance. Its smooth reverse recovery current transition characteristics not only increase efficiency, but reduce EMI and peak reverse voltage stress, eliminating the need for snubbers when used as output rectifiers.

QH12TZ600Q diodes are available in the compact, 2.5 kV isolated TO-220 package, enabling direct mounting to metal heat sinking and facilitating excellent thermal performance. They can be used as a single or interleaved continuous conduction mode (CCM) PFC boost diode or an output rectifier diode in on-board chargers.

New LinkSwitch-TNZ ICs Incorporate Lossless Zero-Cross Detection and X-Capacitor Discharge

Typical discrete AC zero-cross detection circuits require many components and consume as much as half of the standby power budget. Power Integrations’ new LinkSwitch-TNZ IC family solves this problem by combining offline power conversion, lossless zero-cross detection and optional X-capacitor discharge functions in a compact SO-8C package. With integrated lossless AC zero-cross detection, LinkSwitch-TNZ ICs provide best-in-class light-load efficiencies.

LinkSwitch-TNZ ICs provide an accurate signal indicating that the sinusoidal AC line is at zero volts. This signal is used by Smart Home and Building Automation (HBA) products and appliances to control the switching of relays, IGBTs and TRIACs to minimize switching stress and system in-rush current. The device’s detection of the zero-cross point consumes less than 5 mW, allowing systems to reduce standby power losses versus alternative approaches that require 10 or more discrete components and burn 50 to 100 mW of continuous power.

This highly efficient switcher can be used for non-isolated buck and buck-boost power supplies up to 575 mA output current and can provide up to 12 W output for universal input isolated flyback designs. For more information visit www.power.com

PSMA Publishes Technology Report: 3D Power Packaging with Focus on Embedded Passive Component and Substrate Technologies

Comprehensive report is the first to address higher power embeddable passives that will accelerate the development of higher density power sources using new, 3D disruptive packaging technologies

The Power Sources Manufacturers Association (PSMA) Packaging Committee announces the publication of its latest report titled, “3D Power Packaging with Focus on Embedded Passive Component and Substrate Technologies.” This is the third in a series of reports focused on using embedded substrate technology for building power sources. It is the first extensive study of embeddable passive components both available and in development for use in the power path of power sources. The report contains extensive research and product illustrations geared to an audience of technology executives and design engineers.

Miniaturization of passive components without compromising their power handling and efficiency and their integration with actives has always been a key focus for power packaging. There is also an increasing trend to vertical or 3D package integration to address the performance issues by eliminating parasitics from interconnections. Embedding gives lowest package inductance and enables co-integration of power systems and drivers in a single package with direct interconnection between gate driver circuits and switches with shortest interconnection length. This has become even more important with the rapid emergence of wide bandgap power switching devices. This, however, leads to several process integration and reliability challenges that need to be systematically addressed.

Georgia Tech Packaging Research Center, under contract from PSMA systematically surveyed the recent advances in passives, active embedding and 3D passive-active integration to generate this report, with emphasis on 3D power packaging enabled by advances in passive components and embedding of actives in power packages. A detailed literature study was conducted on key advances in embedded passive technologies and related topics. Emerging nanomaterials, processes and technologies are described in detail for inductors, capacitors and resistors. Nanostructured materials provide additional degrees of freedoms in enhancing the properties to improve the performance metrics such as volumetric density and efficiency of the components. Key enabling building-blocks are described for each technology. The manufacturing challenges are also highlighted in advancing the components to improve performance. Industry leaders were surveyed to get the recent technology advances in each category. Roadmaps are projected for passive component advances and active embedding technologies.

The trends and roadmaps in 3D power packaging are also described in three categories: low power (1-100 W), medium power (100-1000 W) and high power (10-100 kW). Integration in each category is classified into lead-frame-based, substrate-embedding based and traditional ceramic substrates. Active embedding with panel-scale substrate manufacturing is also reviewed in detail. Recent innovations in substrate materials and associated reliability challenges such as via cracking, dielectric cracking or electric breakdown are highlighted. Advances in die-attach solutions with sintered nanocopper are reviewed, highlighting the evolution of low-stress sintered copper-based die-attach solutions.

Co-chairs of the PSMA Packaging Committee, Ernie Parker of Crane Aerospace & Electronics and Brian Narveson of Narveson Consulting, described the report as “the first comprehensive document to discuss the challenges companies will face to implement embedded passives in 3D power packaging to create the significantly higher power densities.

The PSMA report on 3D packaging was provided free of charge to PSMA Regular and Associate Company members.  Additional copies may be purchased at the member price of $290. PSMA Affiliate members may also purchase the report for $290. The report is available to non-members for purchase on the PSMA website (www.psma.com/publications) for the price of $3,490.
