General Description

The SN3340 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 chip operates from an input supply between 6V and 18V and provides an externally adjustable output current of up to 750mA.

Depending upon supply voltage and external components, this can provide up to 12 watts of output power.
