CMOS IC

40V/1.2A INTEGRATED

POWER LED DRIVER



DESCRIPTION

The UTC L4120 is a continuous conduction mode inductive

step-down converter, designed for driving single or multiple series

connected LEDs. Using a few external components.

The UTC L4120 has a build-in power switch, based on different

input voltage, The UTC L4120 can drive several 1W or 3W LEDs.

The device has the function of thermal shutdown protection and

LED short-circuit/open-circuit protection.

SOT-89-5



FEATURES

* Up to 1.2A output current

* High efficiency (up to 97%)

* Wide input voltage range: 5V~30V

* Typical ±5% output current accuracy

* Single DIM pin on/off and brightness control using DC voltage or

PWM signal

* Internal thermal shutdown protection.

* Adjustable Constant LED Current
