AOZ1016
EZBuck™ 2A Simple Buck Regulator
General Description
The AOZ1016 is a high efficiency, simple to use, 2A buck
regulator. The AOZ1016 works from a 4.5V to 16V input
voltage range, and provides up to 2A of continuous
output current with an output voltage adjustable down
to 0.8V.
The AOZ1016 comes in an SO-8 package and is rated
over a -40°C to +85°C ambient temperature range.
