TPS5450DDAR Description

Short technical summary and product information.

The Texas Instruments TPS5450DDAR is a versatile step-down (buck) DC/DC converter designed for a wide range of power management applications. It supports an input voltage range from 5.5V to 36V and can deliver up to 5A of continuous output current.

 

The device offers an adjustable output voltage, capable of regulating down to 1.22V with 1.5% initial accuracy. Its internal compensation circuitry minimizes the need for external components, simplifying design. The fixed 500kHz switching frequency allows for the use of smaller filter components, contributing to a compact solution.

 

Key features include overcurrent limiting, overvoltage protection, and thermal shutdown for system protection. The TPS5450DDAR is housed in a thermally enhanced 8-pin SOIC PowerPAD package, suitable for surface mount applications. Its high efficiency, greater than 90%, is achieved through an integrated 110mΩ MOSFET switch.

 

This converter is well-suited for various applications requiring efficient voltage regulation, such as power supplies, battery chargers, and embedded systems where a robust and compact power solution is needed.
