AOZ1015
EZBuck™ 1.5A Synchronous Buck Regulator
General Description
The AOZ1015 is a high efficiency, simple to use, 1.5A
buck regulator. The AOZ1015 works from a 4.5V to
16V input voltage range, and provides up to 1.5A of
continuous output current with an output voltage
adjustable down to 0.8V.
The AOZ1015 comes in an SO-8 package and is rated
over a -40°C to +85°C ambient temperature range.
Features
● 4.5V to 16V operating input voltage range
● 130mΩ internal PFET switch for high efficiency:
up to 95%
● Internal Schottky diode
