FAN602F Datasheet (Fairchild Semiconductor) - Offline Quasi-Resonant PWM Controller

FAN602F, Offline Quasi-Resonant PWM Controller

The FAN602F is an advanced PWM controller aimed at achieving power density of ≥10W/in3 in universal input range AC/DC flyback isolated power supplies.

It incorporates Quasi-Resonant (QR) control with proprietary Valley Switching with a limited frequency variation.

QR switching provides high efficien
