FAN4822 - ZVS Average Current PFC Controller

Description

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.

Features

  • Average current sensing, continuous boost, leading edge PFC for low total harmonic distortion and near unity power factor.
  • Built-in ZVS switch control with fast response for high efficiency at high power levels.
  • Average line voltage compensation with brownout control.
  • Current fed gain modulator improves noise immunity and provides universal input operation.
  • Overvoltage comparator eliminates output “runaway” due to load removal.
  • UVLO, current.
