Bipolar IC

For Power Factor Correction

F_FAA₅₃₃5_1P3_(M3_)/F1_A5P₃₃₂(_PM_(M))/FA5332P(M)

■ Description

■ Dimensions, mm

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.

Á SOP-16

FA5331P(M) is a 1st generation IC and FA5332P(M) is 2nd

generation IC which light-load characteristics are improved.

■ Features

10.06

• 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

0.7

0.40^±0.1

1.27^±0.2

• Undervoltage malfunction prevention function

• Low standby current (90µA typical) for simple start-up circuit

• 16-pin package (DIP/SOP)

Á DIP-16

FA5331P

• ±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.
