EZBuck™ 8 A Synchronous Buck Regulator

General Description

Features

The AOZ1039DI is a high efficiency, easy to use, 8 A

synchronous buck regulator. The AOZ1039DI provides

up to 8 A of continuous output current with an output

voltage adjustable from 1.2 V to 0.8 V when the input

power rail is 12 V. For higher output voltage and/or lower

input voltage, the output current should be derated

according to thermal performance.

z 4.5 V to 18 V operating input voltage range

z Synchronous Buck: 70 mΩ internal high-side switch

and 11 mΩ internal low-side switch (at 12 V)

z Up to 95% efficiency

z Internal soft start

z Output voltage adjustable to 0.8 V

z 8 A continuous output current

z Cycle-by-cycle current limit

z Pre-bias start-up

The AOZ1039DI comes in a DFN5x6 is rated over a

-40 °C to +85 °C operating ambient temperature range.

z Short-circuit protection

z Thermal shutdown

Applications

z Point of load DC/DC converters

z LCD TV

z Set top boxes

z DVD and Blu-ray players/recorders

z Cable modems
