General Description

The SN3350 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 750mA.

Depending upon supply voltage and external components, this can provide up to 30 watts of output power.
