Datasheet Summary
Product Preview Offline Quasi-Resonant PWM Controller
Description The FAN604P 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 overe the inherent limitation of QR switching.
FAN604P burst mode operation with extremely low operating current (300 mA) 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.
FAN604P includes several user configurable Features...
