Beschreibung
This evaluation board user’s manual describes a 65 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 PPS 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 onsemi’s NCP1345 HF PWM controller,NCP4307 synchronous rectified controller, FDMS86180 synchronous MOSFET and NTTFS4C02 Switch MOSFET. This Design Note provides the complete circuit schematic details, PCB and BOM for 65 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 / 3.25 A).This design combined with onsemi’s FUSB15101 PD3.0 protocol controller to provide PD3.0 and PPS 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.NCP1345 is next generation of NCP1342 HF QR controller, it provides precise primary CC also precise primary OVP protection, built in external dual Vcc circuit,improved jittering function which eliminated large output ripple also adaptive gate drive to reduce secondary voltage stress.This design also uses NCP4307 synchronous rectified controller which eliminated external Vcc circuit at low output, also placed on high side or low side.
