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 comprehensive 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 (typ...
