ALPHA & OMEGA SEMICONDUCTOR AOZ1269AQI 28 V/12 A Synchronous EZBuckTM Regulator General Description The AOZ1269AQI is a high-efficiency, easy-to-use DC/DC synchronous buck regulator that operates up to 28 V. The device is capable of supplying 12 A of continuous output current with an output voltage adjustable down to 0.6 V ±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 to 3.5 µS. 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.
