AOZ2337CQI-01

EZBuck™ DC-DC Buck Regulators

Status: Full Production

The AOZ2337CQI-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. 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 20A of continuous output current with an output voltage adjustable from 0.6V to 1.790625V (±2.0%)
