AP3303 - Diodes

AP3303 QUASI-RESONANT PWM CONTROLLER

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, th.

Features

are included, such as brown out protection, cycle-by-cycle current limit, VCC Over Voltage Protection (VOVP), Secondary-side Output OVP (SOVP) and UVP (SUVP), internal OTP, Over Load Protection (OLP) and pins’ fault protection. Combined with Diodes Incorporated’s synchronous controller APR347, the AP3303 system can achieve the higher power conversion efficiency and the better thermal performance.
