Preliminary Data Sheet R2A20118ASP R03DS0002EJ0201 Critical Conduction Mode Interleaved PFC Control IC Rev.2.01 Jan 08, 2016 Description The R2A20118A controls a boost converter to provide an active power factor correction. The R2A20118A is based on R2A20117, and additional functions are OVP2 and Brownout. The R2A20118A adopts critical conduction mode for power factor correction and realizes high efficiency and a low switching noise by zero current switching. Interleaving function improves ripple current on input or output capacitor by 180 degrees phase shift.
