EPC introduces the 40 V, 3 milliohm EPC2055 eGaN^® FET, offering designers a device that is smaller, more efficient, and more reliable than currently available devices for high performance, space-constrained applications.

EL SEGUNDO, Calif. — December 2020 — Efficient Power Conversion Corporation, the world’s leader in enhancement-mode gallium nitride on silicon (eGaN) power FETs and ICs, advances the performance capability of low voltage, off-the-shelf gallium nitride transistors with the introduction of the EPC2055 (3 mΩ, 40 V) eGaN FET. 

Efficient Power Conversion’s EPC9204 and EPC9205 power modules demonstrate the efficiency enhancements and significant size reduction achieved in DC-DC power conversion using high frequency switching eGaN^® power transistors and integrated circuits.

EL SEGUNDO, Calif.— March 2018 — Efficient Power Conversion Corporation (EPC) introduces two new GaN power modules for DC-DC conversion, increasing efficiency across the 48 V to point-of-load power architecture. The EPC9205 is a high-power density PCB-based power module for 48 V – 12 V conversions while the EPC9204 address the 20 V – point-of-load conversion with an ultra-thin profile PCB-based power module.

The EPC9086 high efficiency half-bridge development board can operate up to 10 MHz featuring a 30 V EPC2111 eGaN^® half bridge in combination with the recently introduced high speed Peregrine Semiconductor PE29102 gate driver.

EL SEGUNDO, Calif.—October 2017 — Efficient Power Conversion Corporation (EPC) today announces the availability of The EPC9086 development board, a high efficiency half-bridge development board that can operate up to 10 MHz.  The EPC9086 board measures 2” x 2” and contains a 30 V, 15 A EPC2111 enhancement-mode gallium nitride half bridge in combination with the recently introduced PE29102 gate driver from Peregrine Semiconductor.

EPC2111 GaN half bridge offers power systems designers a solution that increases efficiency for complete overall point-of-load system applications over 85% at 14 A when switching at 5 MHz and over 80% when switching at 10 MHz and converting from 12 V to 1.8 V.

EL SEGUNDO, Calif. — June2017 — EPC announces the EPC2111, 30 V enhancement-mode monolithic GaN transistor half bridge. By integrating two eGaN^® power FETs into a single device, interconnect inductances and the interstitial space needed on the PCB are eliminated.  This increases both efficiency (especially at higher frequencies) and power density, while reducing assembly costs to the end user’s power conversion system. The EPC2111 is ideal for high frequency 12 V to point-of-load DC-DC conversion.

EPC9059 development board showcases industry’s first monolithic half-bridge enhancement-mode gallium nitride (eGaN^®) integrated circuits for high current, high frequency point-of-load applications for increased power density.

EL SEGUNDO, Calif.— January 2016 — Efficient Power Conversion Corporation (EPC) introduces the EPC9059 half-bridge development board for high current, high frequency point-of-load (POL) applications using eGaN ICs to reduce power conversion size. The EPC9059 development board has a 30 V maximum device voltage with a 50 A maximum output current. In this application two 30 V EPC2100 eGaN IC’s operating in parallel with a single onboard gate driver to achieve higher output currents. GaN devices have superior current sharing capability compared to silicon MOSFETs, making them more attractive for parallel operation.

Designers of point of load (POL) converters used in 24 VDC systems traditionally have had to decide between the high cost of an isolated converter and the low frequency and efficiency of a buck converter. When compared with the 12 V POL converter common in computing systems, the higher voltage of the 24 V POL converter increases FET voltage to at least 40 volts to accommodate switch-node ringing and increases commutation and C_OSS losses. eGaN FETs, from EPC, offer ultra-low Q_GD for low commutation losses and low Q_OSS for lower losses when charging and discharging the output capacitance. In addition, the innovative Land Grid Array (LGA), wafer level packaging of EPC’s eGaN FETs allow ultralow inductance in both the high frequency power loop and gate drive loop, and most importantly, the path common to these loops, known as the common source inductance (CSI) to help minimize current commutation losses. Low charge and CSI of eGaN FETs allow designers to push power density higher by pushing frequency higher without the efficiency penalty of traditional MOSFETs.
