EZBuck™ 3A Synchronous Buck Regulator

General Description

Features

The AOZ1031A is a high efficiency, easy to use, 3A

synchronous buck regulator. The AOZ1031A 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.

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

The AOZ1031A comes in a SO-8 package and is rated

over a -40°C to +85°C operating ambient temperature

range.

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

z Cycle-by-cycle current limit

z Pre-bias start-up

z Short-circuit protection

z Thermal shutdown

z SO-8 package

Applications

z Point of load DC/DC converters

z LCD TV

z Set top boxes

z DVD/Blu-ray players/recorders

z Cable modems

z PCIe graphics cards

z Telecom/Networking/Datacom equipment
