Overview
Description
AP3302
QUASI-RESONANT PWM CONTROLLER
Pin Assignments
The AP3302 is a Peak-Current control, Quasi-Resonant (QR) PWM controller which is optimized for high performance, low standby power and cost effective offline flyback converters.
At no load or light load, the IC will enter the burst mode to minimize standby power consumption.
The minimum switching frequency (about 22kHz) is set to avoid the audible noise.
When the load increases, the IC will enter valley lock QR mode with frequency foldback to improve system efficiency and EMI performance.
The maximum switching frequency (about 120kHz) is set to clamp the QR frequency to reduce switching power loss.
Furthermore, the frequency...
