TPS54331QDRQ1 Description

Short technical summary and product information.

The TPS54331QDRQ1 from Texas Instruments is a 3A, 28V input, step-down DC/DC converter featuring SWIFT™ technology and Eco-Mode™. This automotive-qualified buck converter supports an adjustable output voltage down to 0.8V and can deliver up to 3A of continuous output current.

 

Key electrical specifications include a wide input voltage range of 3.5V to 28V and a fixed switching frequency of 570kHz. It utilizes current mode control and includes features like light-load efficiency enhancement with Pulse Skipping Eco-mode™, adjustable soft-start to limit inrush currents, and programmable UVLO threshold. The integrated 80 mΩ high-side MOSFET contributes to its efficiency.

 

Protection features include cycle-by-cycle current limit, frequency fold back, and thermal shutdown protection. The device is available in an easy-to-use 8-pin SOIC package, measuring 4.9 mm × 6 mm.

 

Applications for the TPS54331QDRQ1 include consumer electronics such as set-top boxes, CPE equipment, LCD displays, peripherals, and battery chargers, as well as industrial and car audio power supplies, and 5V, 12V, and 24V distributed power systems.
