AOZ1033AI
EZBuck™ 3A Synchronous Buck Regulator
General Description
The AOZ1033A is a high efficiency, easy to use, 3A
synchronous buck regulator. The AOZ1033A works from
4.5V to 18V input voltage range, and provides up to 3A of
continuous output current with an output voltage adjust-
able down to 0.8V.
The AOZ1033A comes in a SO-8 package and is rated
over a -40°C to +85°C operating ambient temperature
range.
Features
z 4.5V to 18V operating input voltage range
z Synchronous Buck: 80mΩ internal high-side switch
and 30mΩ internal low-side switch with integrated
schottky diode
z High efficiency: up to 95%
z Internal soft start
z Output voltage adjustable to 0.8V
z 3A continuous output current
z Fixed 600kHz PWM operation
z Pulse skipping at light load for high efficiency over
entire load range

Pin Function
Power ground. PGND needs to be electrically connected to AGND.
Supply voltage input. When VIN rises above the UVLO threshold and EN is logic high, the
device starts up.
Analog ground. AGND is the reference point for controller section. AGND needs to be
electrically connected to PGND.
Feedback input. The FB pin is used to set the output voltage via a resistive voltage divider
between the output and AGND.
External loop compensation pin. Connect a RC network between COMP and AGND to
compensate the control loop.
Enable pin. Pull EN to logic high to enable the device. Pull EN to logic low to disable the
device. Do not leave it open.
Switching node. PWM output connection to inductor.
