AOZ1083 Datasheet 1.2A Buck LED Driver

Manufacturer: Alpha & Omega Semiconductors

General Description

The AOZ1083 is a high efficiency, simple to use, 1.2 A buck HB LED driver optimized for general lighting applications.

The AOZ1083 operates from a 3 V to 26 V input voltage range and provides up to 1.2 A of continuous LED current.

The 280 mV LED current feedback voltage minimizes the power dissipation of the external sense resistor.
