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 L3080 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.
