AOZ3010PI
EZBuck™ 2 A Synchronous Buck Regulator
General Description
The AOZ3010PI is a high efficiency, simple to use, 2 A
synchronous buck regulator. The AOZ3010PI operates
from a 4.5 V to 18 V input voltage range, and provides up
to 2 A of continuous output current with an output voltage
adjustable down to 0.8 V.
The AOZ3010PI comes in an exposed pad SO-8
package and is rated over a -40 °C to +85 °C operating
ambient temperature range.
