AOZ1036
EZBuck™ 5A Synchronous Buck Regulator
Not Recommended For New Designs
General Description
Features
The AOZ1036 is a high efficiency, easy to use, 5A
z 4.5V to 18V operating input voltage range
synchronous buck regulator. The AOZ1036 works from
z Synchronous Buck: 55mΩ internal high-side switch
4.5V to 18V input voltage range, and provides up to 5A of
continuous output current with an output voltage
adjustable down to 0.8V.
The AOZ1036 comes in both a 5x4 DFN-8 and an
exposed pad SO-8 package and is rated over a
-40°C to +85°C ambient temperature range.
Replacement Part: AOZ3018PI
