AOZ23695RQI 28 V/25 A VID Control Synchronous EZBuckTM Regulator General Description The AOZ23695RQI is a high-efficiency, easy-to-use DC/DC synchronous buck regulator capable of operation from a 5 V to 28 V input bus. The device is capable of supplying 18 A of continuous output current with an output voltage adjustment from 0 V to 1.8 V by controlling VID0 and VID1 signals. A proprietary constant on-time PWM control with input feed-forward results in ultra-fast transient response while maintaining relatively constant switching frequency over the entire input voltage range. The devices feature multiple protection functions such as VCC under-voltage lockout, cycle-by-cycle current limit, output over-voltage protection, short-circuit protection, and thermal shutdown.
