95VAC-305VAC Input, 50W SEPIC-PFC LED Driver


Design files


The PMP5112 reference design uses the UCC28810 in a single-stage, PFC-SEPIC configuration to drive a 50W LED load. This supply can operate from an input ranging from 85VAC up to 305VAC. It is capable of driving LED strings from 50V up to 100V at a fixed current of 0.5A with efficiency over 90%.

Output voltage options PMP5112.1
Vin (Min) (V) 95
Vin (Max) (V) 305
Vout (Nom) (V) 100
Iout (Max) (A) .5
Output Power (W) 50
Isolated/Non-Isolated Non-Isolated
Input Type AC
