AP39303 Overview
The AP39303 is a highly integrated power switcher with a built-in Quasi-Resonant (QR) PWM controller and a 700V high performance power MOSFET. AP39303 is specially designed for offline power supply that requires ultra-low standby power, high-power density and prehensive protection. Coordinating with secondary side USBPD or quick charger controller to provide a Flyback charger solution.
