AOZ22645QI

EZBuck™ DC-DC Buck Regulators

Status: Full Production

The AOZ22645QI 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 16A of continuous output current with an output voltage adjustment from 0V to 1.8V by controlling VID0 and VID1 signals. The AOZ22645QI is available in a 4 mm × 4 mm QFN-30L package and is rated over a -40°C to +85°C ambient temperature range.
