AOZ1036
EZBuck™ 5A Synchronous Buck Regulator
General Description
The AOZ1036 is a high efficiency, easy to use, 5A
synchronous buck regulator. The AOZ1036 works from
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.
Features
z 4.5V to 18V operating input voltage range
z Synchronous Buck: 55mΩ internal high-side switch
and 19mΩ Internal low-side switch
z High efficiency: up to 95%
z Internal soft start
z Output voltage adjustable to 0.8V
z 5A continuous output current
z Fixed 500kHz PWM operation
z Cycle-by-cycle current limit
