VD_1000W_GAN_PSFB_XDP
Reference design board-1000 W, 400 V phase-shifted full-bridge current-doubler with XDP™ digital power controller and CoolGaN™ HEMT
VD_1000W_GaN_PSFB_XDP is a reference design of an isolated 400 V DC to 12 V DC phase-shifted full-bridge with current-doubler (PSFB-CDR) solution using the XDPP1100-Q040 XDP™ digital power controller. This reference design provides a fully programmable and configurable power converter with an efficiency of up to 95.36% and a power density of 67 W/inch. It has fast line-transient and load-transient performance using a hardware-based PID controller module and best-in-class hardware-based feed-forward (FF) response, enabling superior output voltage regulation under light load conditions. PMBus and I2C communication are integrated to facilitate system configuration and control and telemetry updating and fault monitoring. In addition, this REF_XDP_1000W_GAN_PSFB is equipped with IGT60R070D1 high-voltage (HV) gallium nitride (GaN) FETs, which enable high switching frequency operation at 350 kHz.
