AOZ22421QI 28V/10A Synchronous EZBuckTM Regulator General Description The AOZ22421QI is a high-efficiency, easy-to-use DC/DC synchronous buck regulator that operates up to 28V. The device is capable of supplying 10A of continuous output current with an output voltage adjustable down to 0.8V ±1%. 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 on time can be externally programmed up to1.2µs. The device features multiple protection functions such as VCC under-voltage lockout, cycle-by-cycle current limit, output over-voltage protection, short-circuit protection, and thermal shutdown.
