The EPC9195 synchronous buck converter evaluation board, operates at 750 kHz switching frequency and converts an input voltage of 36 V – 60 V to a regulated 13 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. The combination of Analog Device’s LTC7891 100 V synchronous GaN buck controller with ultra-efficient EPC2619 GaN FETs 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.
