Preliminary Datasheet

R2A20113ASP

Critical Conduction Mode PFC Control IC

Description

R03DS0026EJ0300

Rev.3.00

Nov 02, 2011

The R2A20113A controls a boost converter to provide an active power factor correction.

The R2A20113A adopts critical conduction mode for power factor correction and realizes high efficiency and a low

switching noise by zero current switching.

Because the zero current is detected by using the GND current, the ZCD Auxiliary winding is unnecessary.

The feedback loop open detection, two mode overvoltage protection, overcurrent protection are built in the R2A20113A,

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