AOZ1281DI Description

Short technical summary and product information.

The AOZ1281DI is a high-efficiency, simple-to-use 1.8A buck regulator from Alpha and Omega Semiconductor. It is designed for a wide variety of applications, offering a flexible input voltage range from 3V to 26V and the ability to provide up to 1.8A of continuous output current.

The output voltage is adjustable down to 0.8V, making it suitable for diverse power management needs. The regulator operates with a fixed switching frequency of 1.5MHz in PWM mode, which helps in reducing the required inductor size. Key electrical features include internal compensation, internal soft start, and cycle-by-cycle current limit protection.

This buck regulator is housed in a compact, thermally-enhanced DFN 2x2, 8-lead package, suitable for surface mount applications. It also includes protection features such as short-circuit protection and thermal shutdown, enhancing its reliability in demanding environments.

Applications for the AOZ1281DI include point-of-load DC/DC conversion, set-top boxes, DVD drives, HDD, LCD monitors and TVs, cable modems, and telecom/networking/datacom equipment.
