AOZ23655QI

EZBuck™ DC-DC Buck Regulators

The AOZ23655QI is a high-efficiency, easy-to-use DC/DC synchronous buck regulators capable of operation from a 4V to 28V input bus. The device is capable of supplying 18A of continuous output current with an output voltage adjustment from 0V to 1.8V by controlling VID0 and VID1 signals. The AOZ23655QI is available in a 5 mm × 5 mm QFN-31L package and is rated over a -40°C to +85°C ambient temperature range.
