February 2006
General Description
The AOZ1010 is a high efficiency, simple to use, 2A buck
regulator. The AOZ1010 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 AOZ1010 comes in an SO-8 package and is rated over
a -40°C to +85°C ambient temperature range.
