EZBuck™ 5A Simple Buck Regulator
AOZ1094
General Description
The AOZ1094 is a high efficiency, simple to use, 5A buck
regulator. The AOZ1094 works from a 4.5V to 16V input
voltage range, and provides up to 5A of continuous
output current with an output voltage adjustable down
to 0.8V.
The AOZ1094 comes in SO-8 and DFN-8 packages
and is rated over a -40°C to +85°C ambient temperature
range.
Features
4.5V to 16V operating input voltage range
28m
internal PFET switch for high efficiency:
up to 95%
