EZBuck™ 2 A Synchronous Buck Regulator

General Description

Features

The AOZ1050PI is a high efficiency, easy to use, 2 A

synchronous buck regulator. The AOZ1050PI works from

4.5 V to 18 V input voltage range, and provides up to 2 A

of continuous output current with an output voltage

adjustable down to 0.8 V.

z 4.5 V to 18 V operating input voltage range

z Synchronous Buck: 80 mΩ internal high-side switch

and 50 mΩ internal low-side switch (at 12 V)

z Up to 95 % efficiency

z External soft start

The AOZ1050PI comes in an exposed pad SO-8

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

ambient temperature range.

z Output voltage adjustable to 0.8 V

z 2 A continuous output current

z 500 kHz PWM operation

z Cycle-by-cycle current limit

z Pre-bias start-up

z Short-circuit protection

z Thermal shutdown

z Exposed pad SO-8 package
