USL1601 Datasheet (Unisonic Technologies) - CONSTANT CURRENT CONTROLLER

USL1601, CONSTANT CURRENT CONTROLLER

The UTC USL1601 is a high precision constant current non-isolated buck LED driver controller.

It can operate under universal AC input, also can operate 12V~600V DC input.

The UTC USL1601 integrates 600V power MOSFET, so it can use very few external components achieve excellent constant current perfo
