AOZ2255LQI-31 Description

Short technical summary and product information.

The AOZ2255LQI-31 is a 28V, 12A synchronous EZBuckTM regulator designed for high-efficiency DC/DC conversion. It operates from an input voltage range of 6.5V to 28V and allows for an adjustable output voltage down to 0.6V with ±1.0% accuracy. The regulator utilizes a proprietary constant on-time PWM control with input feed-forward for fast transient response.

 

Key electrical specifications include low RDS(ON) internal NFETs (11mΩ high-side, 7mΩ low-side) and an integrated bootstrap diode. Protection features include VCC under-voltage lockout, cycle-by-cycle current limit, output over-voltage protection, short-circuit protection, and thermal shutdown.

 

This device is supplied in a thermally enhanced 4mm x 4mm QFN-22L package, suitable for surface mounting. The operating ambient temperature range is -40°C to +85°C. Applications include compact desktop PCs, graphics cards, set-top boxes, LCD TVs, cable modems, point-of-load DC/DC converters, and telecom/networking/datacom equipment.
