Overview
IS31LT3353
40V/1A BUCK LED DRIVER WITH INTERNAL SWITCH
October 2014
GENERAL DESCRIPTION
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 current of up to 1A.
The IS31LT3353 includes an integrated output switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current.
The output current can be dynamically adjusted by adding either a digital PWM or analog voltage level signal to t...
