AP3303 Overview
The AP3303 is a peak-current control, Quasi-Resonant (QR) PWM controller which is specially designed for offline power supply that requires ultra-low standby power, high-power density and prehensive protection. It can coordinate with secondary side USBPD or quick charger controller which can provide a flyback charger solution. At no load or light load, the IC will enter the burst mode to minimize standby power...
