L4075 Datasheet (Unisonic Technologies)

L4075, 40V LED DRIVER

The UTC L4075 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 chip operates from an input supply between 6V and 40V and provides an externally
