IS31LT3354 Datasheet (ISSI)

IS31LT3354, 40V LED DRIVER

The IS31LT3354 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 required LED voltage.

The device operates from an input supply between 6V and 40V and provides an externally adjust
