General 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) con-
troller to reduce diode recovery and MOSFET turn-on
The average current boost PFC circuit provides high power
factor (>98%) and low Total Harmonic Distortion (THD).
Built-in safety features include undervoltage lockout, over-
voltage protection, peak current limiting, and input voltage
brownout protection.
The ZVS control section drives an external ZVS MOSFET
which, combined with a diode and inductor, soft switches the
boost regulator. This technique reduces diode reverse recov-
ery and MOSFET switching losses to reduce EMI and maxi-
mize efficiency.
