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.

SOP-8

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, V_CCunder voltage protection, CS resistor

short circuit protection and thermal regulation function.


