Onsemi NCP1343AMDCDBD1R2G | Demoboard EVBUM2818/D

Beschreibung

This evaluation board user’s manual describes a 100 W,Type C interface, universal AC input, constant voltage power supply intended for smart phone, PAD and NB adaptor supporting PD3.0/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 NCP1623 VSFF PFC controller with 2 stage level, NCP1343 Multi−mode HF PWM controller with transient peak excursion power, NCP4307 synchronous rectified controller, onsemi’s FCMT199N60/ FCMT250N65/FDMS86180/NTTFS4C02 MOSFET. This evaluation board user’s manual provides the complete circuit schematic details, PCB and BOM for 100 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 /5 A).
