EZBuck™ 5 A Synchronous Buck Regulator

General Description

Features

The AOZ3018 is a high efficiency, simple to use, 5 A

synchronous buck regulator. The AOZ3018 operates

from a 4.5 V to 18 V input voltage range, and provides up

to 4 A of continuous output current with an output voltage

adjustable down to 0.8 V.



4.5 V to 18 V operating input voltage range

55 mΩ internal high-side switch and 19 mΩ internal

low-side switch (at 12 V)



Up to 95 % efficiency

External soft start

The AOZ3018 comes in an exposed pad SO-8 package

and is rated over a -40 °C to +85 °C operating ambient

temperature range.

Output voltage adjustable to 0.8 V

5 A continuous output current

500 kHz PWM operation

Cycle-by-cycle current limit

Pre-bias start-up

Short-circuit protection

Thermal shutdown

Exposed pad SO-8 package
