EZBuck^TM2A Synchronous Buck Regulator

General Description

Features

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.

 4.5V to 18V operating input voltage range

 Synchronous Buck: 150mΩ internal high-side switch

and 90mΩ internal low-side switch

 Up to 95% efficiency

 Pulse energy mode for high light load efficiency

(Vin=12V, Vo=5V, 83% @10mA)

The AOZ6622DI comes in a DFN 3mm x 3mm package

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

temperature range.

 Output voltage adjustable to 0.8V

 Adjacent pin short protection

 2A continuous output current

 550kHz PWM operation

 Cycle-by-cycle current limit

 Pre-bias start-up

 Short-circuit protection

 Thermal shutdown

Applications

 Point of load DC/DC converters

 LCD TV

 Set top boxes

 DVD / Blu-ray players/recorders

 Cable modems
