Critical Conduction Mode PFC IC

FA1A60N

1. Overview

Datasheet

FA1A60N is a power factor correction control IC operating in critical conduction mode. It realizes low power consumption

by high voltage CMOS process. It is equipped with many functions such as frequency reduction, FB short protection and

double OVP function.

In addition, it includes communication function with Fuji LLC control IC “FA6B20N”. It helps to improve efficiency of PSU,

to optimize the PFC operation and to reduce external components, if both IC is combined.

2. Features

- Operating mode can be switched between burst mode and normal mode by

communication signal from “FA6B20N”. It helps to improve light load

efficiency.

- Combining with “FA6B20N”, operation is optimized according to line voltage

and distortion of line current is improved for wide input voltage range.

- Low standby power due to no input voltage detection resistors

- High-precision over current protection: 0.6V±2%

- Improved power efficiency at light load by frequency reduction

- Reduced audio noise at start up by overshoot reduction and dynamic OVP

- Low current consumption by CMOS process,

5.0 0.25

Start-up: 250µA(typ.), Operating: 0.8mA(typ.)

- Drive circuit for power MOSFET, peak current: source 500mA, sink 1000mA

- Protects the output electrolytic capacitor by the double OVP function, even if

a fault happen in the output detection.

- Short protection at feedback (FB) pin

- Under-voltage Lockout

- Restart timer

- 8-pin package (SOP)

Package：SOP-8
