General 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.
