R2A20113DD/SP
Critical Conduction Mode PFC Control IC
REJ03F0279-0100
Rev.1.00
Oct 10, 2008
Description
The R2A20113 controls a boost converter to provide a active power factor correction.
The R2A20113 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 R2A20113,
and can constitute a power supply system of high reliability with few external parts.
Features
Absolute Maximum Ratings
Supply voltage Vcc: 24 V
Operating junction temperature Tjopr: –40 to +150°C
