EZBuck™ DC-DC Buck Regulators
The AOZ22722QI is an I2C controllable, high efficiency, easy-to-use DC-DC synchronous buck regulator capable of operation from a 6.5 V to 28 V input bus. 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 8A of continuous output current with an output voltage adjustable from 0.7V to 1.15927V (±1.0%).
