The VIPer22 can be used to implement a circuit with more output capability. This is a schematic of the VIPer22 constant current LED drive. You see the VIPer22, the TSM103, and in this case, we also need the PKC136 to clamp the transient at this higher output power. This board is capable of delivering 12 watts of output power and can drive in this configuration from 2 to 8 LEDs in series. By changing jumpers on the board, we can drive 350 milliamps, 700 milliamps, or 1.05 amps.
