FAN4822 Datasheet (Fairchild Semiconductor) - ZVS Average Current PFC Controller

FAN4822, ZVS Average Current PFC Controller

The FAN4822 is a PFC controller designed speciﬁcally for high power applications.

The controller contains all of the functions necessary to implement an average current boost PFC converter, along with a Zero Voltage Switch (ZVS) controller to reduce diode recovery and MOSFET turn-on losses.
