PFC SEPIC for OLED lighting (208V@0.110A non-isolated LED light string)

PMP5242

Overview

The PMP5242 reference design uses the UCC28810 in a single-stage, PFC-SEPIC configuration to drive a 22W LED load. This supply can operate from an input ranging from 85VAC up to 265VAC. It is capable of driving LED strings from 156V up to 208V at a fixed current of 110mA with efficiency over 89%.
