FA5591

Power Supply Control IC(Power Factor Correction)

Fuji Electric 

FA5590N,FA5591N

1. Description

FA5590/FA5591 is power-factor correction converter IC operating in critical conduction mode. It realizes low

power consumption by using high voltage CMOS process. It is equipped with many fault protection functions such

as FB short-circuit detection circuit which stops the operation when abnormal output voltage is detected.

2. Features

 Very Low Standby Power by disusing Input Voltage Detection Resistors

 High-precision over current protection：0.6V±5%

 Improved power efficiency at light load due to Maximum Frequency Limitation

 No Audible Noise at Startup

Soft-Startup and Soft-OVP functions

 Low current consumption by CMOS process

Start-up : 80µA(max.), Operating : 2mA(typ.)

 Enabled to drive power MOSFET directly

Output peak current, source : 500mA, sink : 1000mA

 Open/short protection at feedback (FB) pin

 Under-voltage Lockout

FA5590: 9.6V ON / 9V OFF FA5591:13V ON / 9V OFF

 Overvoltage protection

 Restart timer

 Standby function

 8-pin package (SOP)
