Beschreibung
This design note 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 ON Semiconductor’s NCP1342 HF PWM controller, NCP4306D synchronous rectified controller, NTMFS6B03 synchronous MOSFET and ATP104 Switch MOSFET. This Design Note provides the complete circuit schematic details, PCB and BOM for 45 W Type C Interface PD3.0 Power adapter solution which supports PD output (5 V / 3 A, 9 V / 3 A, 12 V / 3 A, 15 V / 3 A, 20 V / 2.25 A). This design combined with Weltrend WT6632F PD3.0 protocol controller to provide PD3.0 and QC3.0 functions. This design also proposes a dual auxiliary power supply to supply PWM controller, the PWM controller is supplied by high voltage auxiliary voltage at low output voltage and supplied by low voltage auxiliary voltage at high output voltage and also shuts down zener bias of high voltage Vcc while low voltage auxiliary voltage supplies controller. This design also uses NCP4306 synchronous rectified controller to provide high efficiency and also has no external Vcc regulator to supply synchronous controller to ensure controller can works below 3.6 V.
