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.

• 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.
