General Description

The AOZ6763DI is a high efficiency, easy to use, 3A

synchronous buck regulator at high switching frequency

for small form factor solution. The AOZ6763DI 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 0.6V.

The AOZ6763DI comes in a DFN 3mm x 3mm package

and is rated over a -40°C to +85°C operating ambient

temperature range.
