Description
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 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 efficiency and EMI performance. The maximum switching frequency...
