300V GaN Power Transistors for High-Frequency Applications
Efficient Power Conversion (EPC) announces the EPC2025, a 300V power transistor for use in applications requiring high-frequency switching (2ns rise times) in order to achieve higher efficiency and power density. Applications enhanced by higher switching speeds include ultra-high frequency dc-dc converters, medical diagnostic equipment, power inverters, and LED lighting. The EPC2025 has a maximum RDS(on) of 150 mΩ with a 4-A output. It is available in passivated die form with solder bars for efficient heat dissipation and ease of assembly. The EPC2025 measures 1.95 mm x 1.95 mm for increased power density.
“As end-systems increasingly require smaller size dc-dc power converters, especially those used in portable equipment, the demand for corresponding higher speed switching power converters is increasing. The EPC2025 allows power designers to increase the switching frequency of their power conversion systems for increased efficiency and smaller footprint,†said Alex Lidow, EPC’s co-founder and CEO.
The EPC9042 development board is a 300V maximum device voltage, half-bridge with onboard gate driver, featuring the EPC2025, onboard 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 300V EPC2025 eGaN® FET. The EPC2025 eGaN FETs are priced for 1K units at $5.29 each. The EPC9042 development boards are priced at $137.75 each.
