AOZ22701QI

EZBuck™ DC-DC Buck Regulators

Status: Full Production

The AOZ22701QI is an I2 C 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 I2 C 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 0.7V to 1.15927V (±1.0%).
