General Description

The AOZ6762DI is a high efficiency, easy to use, 2A

synchronous buck regulator at high switching frequency

for small form factor solution. The AOZ6762DI 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 0.6V.

The AOZ6762DI features fixed frequency operation at

heavy load and Pulse Energy Mode (PEM) at light load,

providing best efficiency across whole load range.

The AOZ6762DI comes in a DFN 3mm x 3mm 8-lead

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

ambient temperature range.
