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 16th 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 16th 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 16th 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 introduces 100 V, 3.8 milliohm EPC2053 eGaN® FET, joining the EPC2045, EPC2052, and EPC2051 to offer a comprehensive 100 V family of GaN transistors that are more efficient, smaller, and lower cost for high performance 48 V DC-DC conversion.
EL SEGUNDO, Calif. — April 2019 — Efficient Power Conversion Corporation, the world’s leader in enhancement-mode gallium nitride on silicon (eGaN) power FETs and ICs advances the performance capability while lowering the cost of off-the-shelf gallium nitride transistors with the introduction of the EPC2053 (3.8 mΩ, 100 V) eGaN FET.
The EPC2052 offers power systems designers a 100 V, 13.5 mΩ, power transistor capable of 74 A pulsed in an extremely small chip-scale package. In a 48 V – 12 V DC-DC Power Converters these new generation eGaN FETs achieved greater than 97% efficiency at 500 kHz and greater than 96% Efficiency at 1 MHz
EL SEGUNDO, Calif. — March 2019 — Efficient Power Conversion (EPC) announces the EPC2052, a 100 V GaN transistor with a maximum RDS(on) of 13.5mΩ and a 74 A pulsed output current for high efficiency power conversion in a tiny 2.25mm2 footprint.
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.
In this conference GaN market and technology status will be addressed and its future evolution will be debated by mixing visions from designers, manufacturers, and end users.
EL SEGUNDO, Calif. — January 2019 — Efficient Power Conversion (EPC) is joining forces with Yole Développement (Yole) and SEMI to sponsor the first ever ‘GaN Con,’ an industry networking event covering the entire power GaN industry from manufacturers to end users. The theme of GaN Con is “Power GaN: From promises to possible market explosion” and is focused on the emerging GaN market and the state-of-the-art for its underlying technology.
As part of its expansion to support a widening customer base for DC-DC, LiDAR, wireless power applications and beyond, Efficient Power Conversion Corporation has expanded its Asia-based team with new members who are in close proximity to customers in 21 regions throughout Asia Pacific.
EL SEGUNDO, Calif. — November 28, 2018 — To support its accelerating sales growth in Asia, Efficient Power Conversion Corporation (EPC) is proud to announce the expansion of the sales and FAE team in Asia Pacific to support its expanding customer base, maximize new business acquisition and capture new market opportunities.
