AOZ22559QI 25V/15A Synchronous EZBuckTM Regulator General Description The AOZ22559QI is a high-efficiency, easy-to-use DC/DC synchronous buck regulator that operates up to 25 V. The device is capable of supplying 15 A of continuous output current with an output voltage adjustable down to 0.6 V (±1.0%). 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. A low 70 ns minimum on-time enables very low output voltages at ultra-high operating frequencies. Integrated AC ripple injection enables all-ceramic low ESR output filter capacitors and smaller PCB footprint with no external components needed.
