High frequency VR is demanded to meet future microprocessor's requirements. However, the high switching loss and body diode loss suffer the efficiency of VR. Based on two-stage approach, the snubber capacitor paralleled with the top switch is proposed to reduce the switching loss. And a new gate driver is proposed to reduce body diode loss and gate drive loss. The experiment verified these methods
