AOZ3046PI
EZBuck™ 4 A Synchronous Buck Regulator
General Description
The AOZ3046PI is a high efficiency, simple to use, 4 A synchronous buck regulator. The AOZ3046PI operates from a 7.5 V to 18 V input voltage range, and provides up to 4 A of continuous output current with an output voltage adjustable down to 0.8 V.
The AOZ3046PI comes in an exposed pad SO-8 package and is rated over a -40 °C to +85 °C operating ambient temperature range.
