EPC announces the availability of the EPC9157, a 300 W DC-DC demo board in the tiny 1/16th brick size, measuring just 33 mm x 22.9 mm x 9mm (1.3 x 0.9 x 0.35 in). The EPC9157 demo board integrates the Renesas ISL81806 80 V dual synchronous buck controller with the latest-generation EPC2218 eGaN FETs from EPC to achieve greater than 95% efficiency for 48 V input to 12 V regulated output conversion at 25 A.
Brick DC-DC converters are widely used in data center, computing, telecommunication and automotive applications, converting a nominal 48 V to a nominal 12 V distribution bus, among other output voltages. The main trend has been towards higher power density. eGaN® FETs provide the fast switching, high efficiency and small size that can meet the stringent power density requirements of these leading-edge applications. EPC2218 is the smallest high efficiency 100 V eGAN FET on the market (more info).
