The AOZ1033A is a high efficiency, easy to use, 3A
synchronous buck regulator. The AOZ1033A works from
4.5V to 18V input voltage range, and provides up to 3A of
continuous output current with an output voltage adjustable
down to 0.8V.
The AOZ1033A comes in a SO-8 package and is rated
over a -40°C to +85°C operating ambient temperature
range.
