DN05104/D, 45W TYPE-C PD3.0 / QC3.0 Power Adapter Solution Reference Design with WT6632F

DN05104/D, Reference design describes a 45 W, Type C interface PD3.0, universal AC input, constant voltage power supply intended for smart phone, PAD and NB adaptor supporting PD3.0 or QC3.0 protocol, where isolation from the AC mains is required, and low cost, high efficiency, and low standby power are essential. The featured power supply is a simple QR flyback topology utilizing NCP1342 HF PWM controller, NCP4306D synchronous rectified controller, NTMFS6B03 synchronous MOSFET and ATP104 Switch MOSFET. This Design Note provides the complete circuit for 45W Type-C Interface PD3.0 Power adapter solution which supports PD output (5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/2.25A)
