EPC extends Range of GaN Power Transistors to 450V

January 16, 2015 By admin Comments are Off , , , ,

Efficient Power Conversion Corp. (EPC) announces the EPC2027, a 450-V normally-off (enhancement-mode) power transistor for use in applications requiring high frequency switching in order to achieve higher efficiency and power density. Applications enhanced by high voltage higher switching speeds include ultra-high frequency dc-dc converters, medical diagnostic equipment, solar power inverters, and LED lighting.

The EPC2027 has a voltage rating of 450V and maximum RDS(on) of 400mΩ with a 4A output. It is available in passivated die form with solder bars for efficient heat dissipation and ease of assembly. The EPC2027 measures 1.95 mm x 1.95 mm for increased power density.

“As off-line adapters and inverters increasingly push toward smaller size, less weight, and higher power density, the demand for corresponding higher voltage and faster switching speeds is increasing. The 450-V EPC2027 allows power designers to increase the switching frequency of their off-line power conversion systems for increased efficiency and smaller footprint,” said Alex Lidow, EPC’s co-founder and CEO.

The EPC9044 development board, featuring the EPC2027, is in a half-bridge configuration with on-board gate driver, gate drive supply and bypass capacitors. This 2” x 1.5” board has been laid out for optimal switching performance and contains all critical components for easy evaluation of the EPC2027 eGaN® FET. The EPC2027 eGaN FETs are priced for 1K units at $5.81 each. The EPC9044 development boards are priced at $137.75 each. Both are available for immediate delivery from Digi-Key.
