AOZ2263VQI-01 Description

Short technical summary and product information.

The AOZ2263VQI-01 from AOS is a versatile DC-DC synchronous buck regulator capable of operating from a wide 4V to 28V input bus. This device is engineered to provide a substantial 12A of continuous output current, with an output voltage that can be precisely adjusted between 1.05V and 1.125V using VID0 and VID1 control signals.

It utilizes a proprietary constant on-time PWM control with input feed-forward, ensuring rapid transient response and stable switching frequency across the input voltage range. Key protection features include VCC under-voltage lockout, cycle-by-cycle current limit, output over-voltage protection, short-circuit protection, and thermal shutdown.

The regulator is housed in a thermally enhanced 4mm x 4mm QFN-22L package, suitable for surface mount applications. It operates reliably within an ambient temperature range of -40°C to +85°C.

Applications for the AOZ2263VQI-01 include portable computers, servers, graphics cards, set-top boxes, LCD TVs, cable modems, and point-of-load DC-DC converters in telecom and datacom equipment.
