IS32LT3361 - Lumissil

IS32LT3361 INTEGRATED NMOS SWITCH 40V/1.3A LED DRIVER

The IS32LT3361 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 1.3A. The IS32LT3361 includes an integrate.
