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.
FEATURES
* 5V~30V input voltage range
* Simple low parts count
* Typical ±3% output current accuracy
* Up to 500mA output current
* Single DIM pin on/off and brightness control using DC voltage or
PWM signal
* High efficiency up to 97%
* Adjustable constant LED current
* Protection features:
LED open-circuit protection
LED short-circuit protection
Internal thermal shutdown protection.
