Overview
UNISONIC TECHNOLOGIES CO.
, LTD USL3531J Preliminary LINEAR INTEGRATED CIRCUIT NON-ISOLATED BUCK OFFLINE LED DRIVER  DESCRIPTION The UTC USL3531J 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 USL3531J integrates a 500V power MOSFET.
It can achieve excellent constant current performance with very few external components, so the system cost and size are minimized.
The UTC USL3531J offers rich protection functions to improve the system reliability, including LED open circuit protection, LED short circuit protection, VCC under voltage protection, CS resistor short circuit protection and thermal regulation function.
 FEATURES * Critical conduction mode operation * Internal 500V Power MOSFET * Ultra low operating current * No auxiliary winding * ±5% LED output current accuracy * LED short protection * LED open protection * VCC under voltage protection * Current sensing resistor short protection * Thermal regulation function  ORDERING INFORMATION Ordering Number Lead Free Halogen Free USL3531JL-S08-R USL3531JG-S08-R Package SOP-8 SOP-8 Packing Tape Reel USL3531JG-S08-R (1)Packing Type (2)Package Type (3)Green Package (1) R: Tape Reel (2) S08: SOP-8 (3) G: Halogen Free and Lead Free, L: Lead Free  MARKING 876 5 UTC USL3531J 1234 Date Code L: Lead Free G: Halogen Free Lot Code www.
