Features  
General Description  
• 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  
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  
losses.  
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.  
• UVLO, current limit, and soft-start  
• Precision 1.3% reference  
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.
