General Description

The AOZ6689CI is a high efficiency, easy to use, 3A

synchronous buck regulator at high switching frequency

for small form factor solution. The AOZ6689CI 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 AOZ6689CI comes in an ultra thin TSOT23-6L

package and is rated from -40°C to +125°C junction

temperature range.
