IS31LT3350 Datasheet (Lumissil)

IS31LT3350, 40V LED DRIVER

The IS31LT3350 is a continuous mode inductive step-down converter, designed for driving a single LED or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage.

The chip operates from an input supply between 6V and 40V and provides an externally adjustable output
