General Description

The AX2021 is a continuous conduction mode inductive step-down converter, designed for driving single or multiple series connected LED efficiently from a voltage source higher than the total LED chain voltage.

The device operates from an input supply between 8V and 32V and provides an externally adjustable output current of up to 0.45A.

Depending upon the supply voltage and external components, the AX2021 can provide more than 15 watts of output power.
