AOZ6622DI Datasheet 2a Synchronous Buck Regulator

Manufacturer: Alpha & Omega Semiconductors

Overview: AOZ6622DI EZBuckTM 2A Synchronous Buck Regulator General.

General Description

The AOZ6622DI is a high efficiency, easy to use, 2A synchronous buck regulator.

The AOZ6622DI works from 4.5V to 18V input voltage range, and provides up to 2A of continuous output current with an output voltage adjustable down to 0.8V.

The AOZ6622DI comes in a DFN 3mm x 3mm package and is rated over a -40°C to +85°C operating ambient temperature range.

Key Features
