General Description

The BL9581 is a continuous mode inductive step-down converter, designed for driving single or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage.

The device operates from an input supply between 6V and 36V and provides an externally output current up to 1.2A.

Depending upon supply voltage and external components, this can provides up to 24 watts of output power.
