TPS544B20RVFT Description

Short technical summary and product information.

The Texas Instruments TPS544B20RVFT is a high-performance, 20A synchronous buck converter from the SWIFT family. It is designed to operate from an input voltage range of 4.5V to 18V, offering an adjustable output voltage from 0.6V to 5.5V.

 

Key electrical specifications include a maximum output current of 20A, a typical quiescent current of 0.008A, and a selectable switching frequency. The converter features PMBus programmability and monitoring, along with adaptive voltage scaling, adjustable current limit, and overcurrent protection.

 

Packaged in a 40-LQFN-CLIP (7x5) surface-mount configuration, the TPS544B20RVFT operates within an ambient temperature range of -40°C to 125°C. Its design incorporates features like differential remote sense, power good indication, pre-bias start-up, and soft-start for robust power delivery.

 

This buck converter is suitable for various power management applications requiring high current density and precise voltage regulation. Its features like synchronous rectification and D-CAP/D-CAP2 mode control contribute to its efficiency and performance.
