AOZ3024PI
EZBuck™ 3 A Synchronous Buck Regulator
General Description
The AOZ3024PI is a high efficiency, easy to use, 3 A
synchronous buck regulator. The AOZ3024PI works from
4.5 V to 18 V input voltage range, and provides up to 3 A
of continuous output current with an output voltage
adjustable down to 0.8 V.
The AOZ3024PI comes in an exposed pad SO-8
package and is rated over a -40 °C to +85 °C operating
ambient temperature range.
