New EPC GaN Power FETs target High Frequency Applications
450V power transistors are capable of 4ns rise times
EPC has announced the EPC2027, a 450V 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 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 450V 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 1.5in board has been laid out for optimal switching performance and contains all critical components for easy evaluation of the EPC2027 eGaN FET.
