DESCRIPTION

The UTC L3060 is a continuous conduction mode inductive

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

connected LEDs efficiently from a voltage source higher than the

total LEDs chain voltage. The device provides an externally

adjustable output current of up to 500mA for a single LED. A

dedicated DIM pin accepts either a DC voltage (0.5V~2.5V)

dimming or a wide range of pulsed dimming. Applying a voltage of

0.3V or lower to the DIM pin turns the output off and switches the

device into a low current standby state.

The UTC L3060 has a build-in power switch, based on different

input voltage, UTC L3060 can drive several 1W or 2W LEDs.


