Preliminary

CMOS IC

NON-ISOLATED BUCK

OFFLINE LED DRIVER



DESCRIPTION

The UTC USL3532K 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 USL3532K 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 USL3532K 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.


