GaN FETs Deliver Benchmark Power Density and Efficiency for DC/DC Conversion

The newly released EPC9195 synchronous buck converter reference design board, operating at 750 kHz switching frequency, converts an input voltage of 36 V - 48 V to a regulated 13.5 V output. It delivers up to 16 A in a very small footprint of 28 mm x 14 mm and with a profile lower than 5 mm (3.5 mm inductor height). This type of high-density DC/DC converter is used to convert the 48 V DC input from batteries or chargers to a regulated typical 12 V load. 48 V input is getting popular due to USB PD 3.1 efforts to increase power and to reduce cabling for up to 240W. The combination of ADI’s new LTC7891 100V synchronous GaN buck controller with ultra-efficient EPC2619 GaN FETs from EPC helps enable a super small and highly efficient solution with 96.4% efficiency at 48 V to 13.5 V and 16 A continuous current.
