Overview
UNISONIC TECHNOLOGIES CO.
, LTD USL1601 Preliminary CONSTANT CURRENT CONTROLLER FOR NON-ISOLATED BUCK LED DRIVER CMOS IC  DESCRIPTION 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 performance.
The UTC USL1601 uses high precision current sense circuit and patent method for constant current control, to achieve high precision output current and excellent line regulation.
The UTC USL1601 operates in inductor current critical mode.
The LED current is constant over wide range of inductance variation and the LED output voltage, so the load regulation is excellent.
The UTC USL1601 operation current is 200µA only, so the auxiliary winding is not needed.
It can simplify the system design and reduce the system cost.
The UTC USL1601 offers rich pr...
