USL1601 controller equivalent, constant current controller.
* Inductor current critical mode, No need to compensate the inductance variation * 600V MOSFET integrated * ±3% LED current accuracy * Source driver structure, Not need .
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 c.
