General 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.
