FA5331P中文资料富士通数据手册PDF规格书

■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.

■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.
