L4075 Datasheet 40v Led Driver

Manufacturer: Unisonic Technologies

Overview: UNISONIC TECHNOLOGIES CO., LTD L4075 Preliminary 40V LED DRIVER WITH INTERNAL SWITCH.

General Description

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 adjustable output current of up to 400mA.

Depending upon supply voltage and external ponents, this can provide up to 30W of output power.
