FAN604H Offline Quasi-Resonant PWM Controller The FAN604H 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 efficiency by reducing switching losses while Valley Switching with a limited frequency variation bounds the frequency band to overcome the inherent limitation

FAN604H Features

* mWSaver® burst mode operation with extremely low operating current (300 μA) and significantly reduces standby power consumption to meet the most stringent efficiency regulations such as Energy Star’s 5-Star Level and CoC Tier II specifications. FAN604H includes several user configurable features aim
