AOZ22645QI 28V/16A VID Control Synchronous EZBuckTM Regulator General Description The AOZ22645QI is a high-efficiency, easy-to-use DC/ DC synchronous buck regulators capable of operation from a 4V to 28V input bus. The device is capable of supplying 16A of continuous output current with an output voltage adjustment from 0V to 1.8V 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.
