AOZ1280CI Description

Short technical summary and product information.

The AOZ1280CI is a simple and efficient 1.2A buck regulator designed for DC/DC conversion applications. It operates with an input voltage range of 3V to 26V and provides up to 1.2A of continuous output current. The output voltage is adjustable down to 0.8V, offering flexibility for various designs.

 

This regulator features a fixed 1.5MHz PWM switching frequency, which helps reduce the size of external inductors. It boasts high efficiency, up to 95%, and includes internal compensation, soft start, and cycle-by-cycle current limit for robust operation. Protection features include short-circuit protection and thermal shutdown.

 

The AOZ1280CI is housed in a compact SOT-23-6 package, making it suitable for space-constrained applications. It is rated for an operating ambient temperature range of -40°C to +85°C.

 

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