AOZ1210
EZBuck™ 2A Simple Buck Regulator
General Description
The AOZ1210 is a high efficiency, simple to use, 2A buck
regulator flexible enough to be optimized for a variety of
applications. The AOZ1210 works from a 4.5V to 27V
input voltage range, and provides up to 2A of continuous
output current on each buck regulator output. The output
voltage is adjustable down to 0.8V.
