UNISONIC TECHNOLOGIES CO., LTD L3060
30V/500mA HIGH DIMMING RATIO LED CONSTANT CURRENT DRIVER
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.
