AOZ2262DQI-10 Datasheet | Alpha & Omega Semiconductors

28V/10A Synchronous EZBuck TM Regulator General Description The AOZ2262DQI-10 is a high-efficiency, easy-to-use DC/ DC synchronous buck regulator that operates up to 28 V. The device is capable of supplying 10 A of continuous output current with an output voltage adjustable down to 0.8 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 1.3 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. The AOZ2262DQI-10 is available in a 4mm×4mm QFN22L package and is rated over a -40°C to +85°C ambient temperature range.
