Sensitron introduces the SPG025N035P1B GaN half-bridge module using the 350 V EPC2050 eGaN^® FET from Efficient Power Conversion (EPC)

EL SEGUNDO, Calif.— May 2022, Reducing size and cost were key concerns of Sensitron when designing their latest generation GaN power modules. By replacing traditional silicon FETs with EPC’s 350 V, EPC2050 GaN FET, Sensitron was able to reduce the size of their solution by 60% while also improving the module’s already excellent junction-to-case thermal conduction. The SPG025N035P1B from Sensitron is a high-power density 350 V, 20 A GaN half bridge with an integrated gate drive, optimized for stray inductance and switching performance at 500 khz. Rated at 20 A, the module can be used to control over 3 kW. Sensitron’s proprietary topside cooling technology on this ultra-small, lightweight high power density package (1.10" x 0.70" x 0.14") allows for optimal thermal performance. The SPG025N035P1B was designed for commercial, industrial, and aerospace applications.

The EPC7019 has a total dose rating greater than 1 Mrad and SEE immunity for LET of 85 MeV/(mg/cm²). These devices are offered in a chip-scale package, the same as the commercial eGaN FET and IC family.  Packaged versions will be available from EPC Space.

Efficient Power Conversion (EPC) introduces a new family of radiation-hardened (rad-hard) gallium nitride (GaN) products for power conversion solutions in critical spaceborne and other high reliability environments.

EL SEGUNDO, Calif.— June 2021 — EPC announces the introduction of a new family of radiation-hardened gallium nitride transistors and integrated circuits. With higher breakdown strength, faster switching speed, higher thermal conductivity and lower on-resistance, power devices based on GaN significantly outperform silicon-based devices. The lower resistance and gate charge enable faster power supply switching frequencies resulting in higher power densities, higher efficiencies, and more compact and lighter weight circuitry for critical spaceborne missions. Gallium nitride is also inherently radiation tolerant, making GaN-based devices a reliable, higher performing power transistor option for space applications.

EL SEGUNDO, Calif. — December 2020 — BrightLoop Converters has greatly reduced the size, cost and improved reliability of its latest BB SP DC-DC buck converters thanks to Efficient Power Conversion Corporation’s (EPC) EPC2029 enhancement-mode gallium nitride (eGaN^®) FET transistors. By switching from silicon (Si) transistors to gallium nitride (GaN), BrightLoop was able to increase the switching frequency of their design from 200 kHz to 600 kHz, while keeping the same efficiency. This design change increased the power density of the solution by a factor of approximately two and this resulted in lower cost by enabling the implementation of a smaller enclosure.

EPC’s EPC2029 is an 80 V, 48 A eGaN^® FET featuring a 1 mm ball pitch. The wider pitch allows for placement of additional and larger vias under the device to enable high current carrying capability despite the extremely small 2.6 mm x 4.6 mm footprint.

The EPC2152 ePower™ Stage enables higher performance and smaller solution size for high power density, low-cost DC-DC conversion demonstrated in the EPC9151 power module.

EL SEGUNDO, Calif.— December, 2020 — EPC announces the availability of the EPC9151, a 300 W bidirectional DC-DC voltage regulator in the in the very small 16^th brick format which is just 33 mm x 22.9 mm (1.3 x 0.9 in). The EPC9151 power module features Microchip’s dsPIC33CK digital signal controller (DSC) with the EPC2152 ePower™ Stage integrated circuit from EPC to achieve greater than 95% efficiency in a 300 W 48 V to/from 12 V converter design.  Additional phases can be added to this scalable 2-phase design to further increase power.

The combination of Microchip Technology’s digital signal controllers with ultra-efficient eGaN^® FETs from EPC (Efficient Power Conversion) enable best-in-class power density of 730 W/in³ for high efficiency, low cost DC-DC Conversion.

EL SEGUNDO, Calif.— July, 2020 — EPC announces the availability of the EPC9143, a 300 W DC-DC voltage regulator in 16^th brick size. The EPC9143 power module integrates Microchip’s dsPIC33CK digital signal controller (DSC) with the latest generation EPC2053 eGaN FETs from EPC to achieve 96% efficiency in a 48 V input to 12 V output conversion at 25 A.  The switching frequency of 500 kHz enables the 300 W in the very small 16^th brick format which is just 33 mm x 22.9 mm (1.3 x 0.9 in). Additional phases can be added to this scalable 2-phase design to further increase power. The flexibility of the Microchip digital controllers allows the input voltage to be adjusted from 8 V – 72 V and the output voltage from 3.3 V – 25 V.

Efficient Power Conversion (EPC) has recently introduced two new, 100V, GaN devices that are able to handle 48V server and automotive needs. I will be examining the 48V server power solutions to the processor as well as in automotive and energy storage systems (See my article Bi-directional DC/DC power supplies: Which way do we go?) bi-directional supplies, in an EDN exclusive article coming up in the near future. GaN power transistors MUST be a part of these kinds of architectures; from my point-of-view there is no better alternative.

EPC’s Phase Ten Reliability Report adds to the growing knowledge base published in the first nine reports. With this report, EPC has stress-tested over 30,000 parts for a total of over 18 million hours without failure.  There have been no field failures in over two years despite shipping millions of parts.

EL SEGUNDO, Calif.— February 2019 — EPC announces its Phase Ten Reliability Report, documenting the test results leading to the successful completion of automotive AEC-Q101 qualification. AEC-Q101 demands the highest level of reliability standards for power FETs, requiring not only zero datasheet failures, but also low parametric drift during stress testing.  Of note is that EPC’s WLCS packaging passed all the same testing standards created for conventional packaged parts, demonstrating that the superior performance of chip-scale packaging does not compromise ruggedness or reliability.
