Strengthening the link between the real and the digital worldVD_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 I2 C 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.
