Overview

NEW PRODUCT A P39303 Description 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 comprehensive protection.
Coordinating with secondary side USBPD or quick charger controller to provide a Flyback charger solution.
At no load or light load, the IC will enter the burst mode to minimize standby power consumption.
The minimum switching frequency (typical: 24kHz) is set to avoid the audible noise.
When the load increases, the IC will enter QR mode with frequency foldback to improve system...
