1. Description

FA5612/13 is control IC for power factor correction converter. It realizes low power consumption by using high voltage

CMOS process. Thanks to a average current control, a stable operation is obtained, whereby a power factor of 99% or

more is easily available. DC output voltage is controlled under a wide range of load from rated to no load. Further, a

unique switching frequency diffusion function incorporated simplifies the line filter.

2. Features

▪ Unique switching frequency diffusion function incorporated

▪ Selectable switching frequency : Diffuse or Fix (60 kHz, 65 kHz)

▪ High-precision over current protection : 0.5V ± 5%

▪ No audible noise at startup by dynamic OVP circuit

▪ Low current consumption by high voltage CMOS process

Operating : 2mA (typ.)

▪ Enabled to drive power MOSFET directly.

Output peak current, source : 1.5A, sink : 1.5A.

▪ Open/short protection at feedback (FB) pin

▪ Under-voltage lockout

FA5612 : 9.6V ON / 9V OFF FA5613 : 13V ON / 9V OFF

▪ 8-pin package: SOP-8, DIP-8
