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.

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 (90
μ
A 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.
