AOZ2231CQI-01 I2C Controllable 28V/4A Synchronous EZBuckTM Regulator General Description Features The AOZ2231CQI-01 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 1.790625V to 0.6V (±2.0%).  Wide input voltage range – 6.5V to 28V
пЃ¬ 4A continuous output current
пЃ¬ Output voltage adjustable from 0.6V to 1.790625V in 9.375mV
пЃ¬ В±2.0% output voltage accuracy for I2C control
 Low RDS(ON) internal NFETs – 28m high-side
The AOZ2231CQI-01 integrates an internal linear
regulator to generate 5.3V VCC from input. If input
voltage is lower than 5.3V, the linear regulator operates
at low drop output mode, then VCC voltage is equal to
input voltage minus the drop-output voltage of the
internal linear regulator. – 28m low-side
