AOZ2236CQI-02
EZBuck™ DC-DC Buck Regulators
Status: Full Production
The AOZ2236CQI-02 is an I2C controllable, high-efficiency, easy-to-use DC-DC synchronous buck regulator capable of operation from a 6.5V to 24V 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 15A of continuous output current with an output voltage adjustable from 1.790625V to 0.6V (±2.0%)
