EPC Launches 40 V eGaN FET Ideal for High Power Density Solutions for USB-C Battery Chargers and Ultra-thin Point-of-Load Converters

December 17, 2020 by Hailey Stewart

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.

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.

This device is ideal for applications with demanding requirements for performance in space-constrained form factors including USB-C battery chargers and ultra-thin point-of-load (POL) converters. Other low-voltage applications benefiting from the fast-switching speeds and ultra-high efficiency of the EPC2055 include LED lighting, 12 V – 24 V input motor drivers, and lidar systems for robotics, drones, and autonomous cars.

According to Alex Lidow, EPC’s co-founder and CEO, “The EPC2055 is a very good example of the rapid evolution of GaN FET technology. This 40-volt device offers both smaller size and reduced parasitics compared with previous-generation 40 V GaN FETs and at a lower cost; thus, offering designers both improved performance and cost savings.”


Development Board

The EPC90132 development board is a 40 V maximum device voltage, 25 A maximum output current, half-bridge with onboard gate drives, featuring the EPC2055 eGaN FETs. This 2” x 2” (50.8 mm x 50.8 mm) board is designed for optimal switching performance and contains all critical components for easy evaluation of the EPC2055.   Both the EPC2055 and EPC90132 are available to order from Digi-Key at


About EPC

EPC is the leader in enhancement-mode gallium nitride-based power management devices. EPC was the first to introduce enhancement-mode gallium-nitride-on-silicon (eGaN) FETs as power MOSFET replacements in applications such as DC-DC converters, wireless power transfer, envelope tracking, RF transmission, power inverters, remote sensing technology (lidar), and class-D audio amplifiers with device performance many times greater than the best silicon power MOSFETs. EPC also has a growing portfolio of eGaN-based integrated circuits that provide even greater space, energy, and cost-efficiency.
