TPS54317RHFT Description

Short technical summary and product information.

The Texas Instruments TPS54317RHFT is a high-efficiency synchronous step-down (buck) converter from the SWIFT family. It is designed for low-voltage, high-density systems requiring point-of-load regulation.

 

This converter features integrated 60mΩ MOSFET switches, enabling it to deliver up to 3A of continuous output current. The output voltage is adjustable down to 0.9V with a high accuracy of 1%. The switching frequency can be adjusted from 280 kHz to 1600 kHz, offering design flexibility. It is externally compensated, allowing for optimized transient response.

 

The TPS54317RHFT operates over an input voltage range of 3V to 6V and has an operating temperature range of -40°C to 125°C (TJ). It is housed in a compact 24-VQFN (5x4mm) package, reducing board space. The device includes protection features such as peak current limit and thermal shutdown.

 

Applications include low-voltage power distribution at 5V or 3.3V, point-of-load regulation for high-performance processors like DSPs, FPGAs, and ASICs, as well as broadband and networking equipment.
