Critical conduction mode PFC IC

FA1B00N

Datasheet

1．Overview

FA1B00N 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: 0.65V±2%

• Improved power efficiency at light load due to Maximum

Frequency Limitation

• No Audible Noise at Startup by overshoot reduction circuit

• Low current consumption by CMOS process

• Start-up : 300µA(max.), Operating : 1.2mA(typ.)

5.0 0.25

• Enabled to drive power MOSFET directly

• Output peak current, source : 0.5A, sink : 1A

• Open/short protection at feedback (FB) pin

1.27

• Under-voltage Lockout, 13V ON / 9V OFF

• External signal-linked ON/OFF function built in FB pin

Package：SOP-8

• 8-pin package: SOP-8
