General Description

The AOZ1092D is a high efficiency, simple to use, 3A

buck regulator. The AOZ1092D works from a 4.5V to 16V

input voltage range, and provides up to 3A of

continuous output current with an output voltage

adjustable down to 0.8V.

The AOZ1092D comes in 4x5 DFN-8 packages and is

rated over a -40°C to +85°C ambient temperature range.
