SN3340 350mA LED driver

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 o.
