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.
The feedback loop short detection, two modes overvoltage protection and OVP2, overcurrent protection, overcurrent timer latch protection, and ZCD open detection are built in the R2A20118A, and can constitute a power supply system of high reliability with few external parts.
