The R2A20131 is power factor correction control IC of continuous conduction mode.
The R2A20131 is built in Load Tracing Boost, Brownout, Over Voltage Protection, Over Current Protection, FeedBack loop Open detection and Power Good Function.
Load tracing boost function bring improvement of efficiency at light load with few external parts.
The feedback loop open detection, and over current protection are built in the R2A20131, and can constitute a power supply system of high reliability with few external parts.
Power Good Function monitors PFC output voltage and can adjust no-good level.
