Bipolar IC For Power Factor Correction
Description FA5331P(M) and FA5332P(M) are control ICs for a power factor correction system. These ICs use the average current control system to ensure stable operation. With this system, a power factor of 99% or better can be achieved. FA5331P(M) is a 1st generation IC and FA5332P(M) is 2nd generation IC which light-load characteristics are improved. n Features • Drive circuit for connecting a power MOS-FET(Io =±1.5A) • Pulse-by-pulse overcurrent and overvoltage limiting function • Output ON/OFF control function by external signals • External synchronizing signal terminal for synchronous operation with other circuits • Undervoltage malfunction prevention function • Low standby current (90mA typical) for simple start-up circuit • 16-pin package (DIP/SOP) • ±2% accuracy reference voltage for setting DC output and overvoltage protection [FA5332P(M) only] • When there is a possibility of light-load operation, FA5332P(M) is suitable.
