PFC SEPIC (208V@0.110A Non-isolated LED String) for OLED Lighting


Design files


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%.
