AOZ1084 Datasheet 1.2a Buck Led Driver

Manufacturer: Alpha & Omega Semiconductors

Overview: AOZ1084 1.2A Buck LED Driver General.

General Description

The AOZ1084 is a high efficiency, simple to use, 1.2A buck HB LED driver optimized for general lighting applications.

The AOZ1084 works from a 4.5V to 36V input voltage range, and provides up to 1.2A of continuous LED current.

The 160mV LED current feedback voltage minimizes the power dissipation of the external sense resistor.
