TPS54373PWPR Description

Short technical summary and product information.

The Texas Instruments TPS54373PWPR is a high-efficiency synchronous buck converter designed for low-voltage, high-density distributed power systems. It supports an input voltage range from 3V to 6V and can deliver up to 3A of continuous output current.

 

This device features an adjustable output voltage down to 0.9V with 1.0% accuracy. The switching frequency can be fixed at 350kHz or 550kHz, or adjusted from 280kHz to 700kHz, and is synchronizable up to 700kHz. It includes features such as Enable, Frequency Synchronization, Power Good, and Pre-Bias Start-Up, along with Synchronous Rectification for improved efficiency.

 

The TPS54373PWPR is housed in a 20-pin HTSSOP package, measuring 6.5mm x 6.4mm. The integrated MOSFET switches are rated at 60mΩ for high efficiency. The converter is protected by peak current limit and thermal shutdown.

 

Applications include point-of-load regulation for high-performance DSPs, FPGAs, ASICs, and microprocessors, as well as broadband, networking, and optical communications infrastructure.
