Additional Infomation About Product

www.fairchildsemi.com FAN4822 ZVS Average Current PFC Controller Features General Description Average current sensing, continuous boost, leading edge The FAN4822 is a PFC controller designed specically for PFC for low total harmonic distortion and near unity high power applications. The controller contains all of the power factor functions necessary to implement an average current boost Built-in ZVS switch control with fast response for high PFC converter, along with a Zero Voltage Switch (ZVS) con- efciency at high power levels troller to reduce diode recovery and MOSFET turn-on Average line voltage compensation with brownout control losses. Current fed gain modulator improves noise immunity and provides universal input operation The average current boost PFC circuit provides high power Overvoltage comparator eliminates output runaway due factor (>98%) and low Total Harmonic Distortion (THD). to load removal Built-in safety features include undervoltage lockout, over- UVLO, current limit, and soft-start voltage protection, peak current limiting, and input voltage Precision 1.3% reference 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 efciency.
