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.
