Preliminary
30V/800mA INTEGRATED
POWER LED DRIVER
CMOS IC
 DESCRIPTION
The UTC L3080 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 L3080 has a build-in power switch, based on different
input voltage, The UTC L3080 can drive several 1W or 3W LEDs.
The device has the function of thermal shutdown protection and
LED short-circuit/open-circuit protection.
 FEATURES
* Up to 800mA 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
* LED open-circuit protection
* LED short-circuit protection
* Internal thermal shutdown protection.
* Adjustable Constant LED Current
