AOZ2231CQI-11 I2C Controllable 28V/4A Synchronous EZBuckTM Regulator General Description The AOZ2231CQI-11 is an I2C controllable, high efficiency, easy-to-use DC-DC synchronous buck regulator capable of operation from a 6.5V to 28V 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 4A of continuous output current with an output voltage adjustable from 0.9V to 1.190625V (±2.0%). The AOZ2231CQI-11 integrates an internal linear regulator to generate 5.3V VCC from input. If input voltage is lower than 5.
