AOZ2338CQI-01
EZBuck™ DC-DC Buck Regulators
The AOZ2338CQI-01 is an I2C controllable, high efficiency, easy-to-use DC-DC synchronous buck regulator capable of operation from a 6.5V to 26V input bus. The ability to control the output voltage using the I2C bus simplifies converter design for microprocessors or SoCs that require dynamic voltage scaling or voltage margining. The device is capable of supplying 25A of continuous output current with an output voltage adjustable from 0.6V to 1.790625V (±2.0%). The AOZ2338CQI-01 is available in a 5 mm × 5 mm QFN-28L package and is rated over a -40°C to +85°C ambient temperature range.
