Data Sheet

R2A20112SP/DD

Critical Conduction Mode Interleaved PFC Control IC

R19DS0079EJ0400

Rev.4.00

Dec 13, 2014

Description

The R2A20112 controls a boost converter to provide an active power factor correction.

The R2A20112 adopts critical conduction mode for power factor correction and realizes high efficiency and a low

switching noise by zero current switching.

Interleaving function improve ripple current on input or output capacitor by 180 degrees phase shift.

The feedback loop open detection, two mode overvoltage protection, overcurrent protection are built in the R2A20112,

and can constitute a power supply system of high reliability with few external parts.
