IS31LT3353 Datasheet (ISSI) - 40V/1A BUCK LED DRIVER

IS31LT3353, 40V/1A BUCK LED DRIVER

The IS31LT3353 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
