AOZ1280CI Description

Short technical summary and product information.

The AOZ1280CI is a versatile 1.2A non-synchronous buck regulator designed for a wide range of applications. It offers a broad input voltage range from 3V to 26V, making it suitable for various power supply needs. The output voltage is adjustable down to 0.8V, providing flexibility for different system requirements.

This regulator features a fixed 1.5MHz PWM switching frequency, which allows for the use of smaller inductor sizes, contributing to a more compact design. With an internal NMOS switch having an Rds(on) of 240mΩ, it achieves high efficiency of up to 95%. The device includes internal compensation and soft-start functionality, simplifying external component selection and improving system stability.

Key protection features include cycle-by-cycle current limit, short-circuit protection, and thermal shutdown, ensuring reliable operation under fault conditions. The AOZ1280CI is housed in an industry-standard SOT23-6L package, suitable for surface mount applications. Its operating ambient temperature range is -40°C to +85°C.

Applications for the AOZ1280CI include point-of-load DC/DC conversion, set-top boxes, DVD drives, HDD, LCD monitors and TVs, cable modems, and telecom/networking equipment.
