Product Summary
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.
Parametrics

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 (90μA 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.
