TPS54394PWPR Description

Short technical summary and product information.

The Texas Instruments TPS54394PWPR is an integrated circuit designed for DC/DC power conversion. This device functions as a step-down (buck) converter, featuring dual channels and synchronous rectification for improved efficiency. It supports an adjustable output voltage ranging from 0.76V to 7V, with a maximum input voltage of 18V and a minimum of 4.5V. The part can deliver up to 3A of output current per channel.

 

Key electrical characteristics include a switching frequency of 700kHz and a typical quiescent current of 1.2mA. The operating temperature range is specified from -40°C to 85°C. The device is supplied in a 16-HTSSOP package, suitable for surface mounting.

 

This component is designed for applications requiring efficient power regulation. Its integrated FETs and D-CAP2 control mode contribute to fast transient response and compatibility with ceramic output capacitors. The device also includes features like power good indication and soft start functionality.
