USL3532 Datasheet | Unisonic Technologies

UNISONIC TECHNOLOGIES CO., LTD Preliminary LINEAR INTEGRATED CIRCUIT NON-ISOLATED BUCK OFFLINE LED DRIVER - DESCRIPTION The UTC USL3532 is a high performance, high precision and low cost constant current LED driver for non-isolated buck application. The device operates in critical conduction mode and is suitable for 85V~265V universal input offline LED lighting. It operates in critical conduction mode, the output current does not change with the inductance and LED output voltage. The UTC USL3532 integrates a 500V power MOSFET. It can achieve excellent constant current performance with very few external ponents, so the system cost and size are minimized. The UTC USL3532...
