Featured evaluation modules


The UCD90320EVM-783 evaluation module contains a UCD90320 device, two step-down power stages using the TPS54678 synchronous step-down switcher with integrated FET (SWIFT™), two TPS7A84 LDOs, a TPS73633 LDO, and a REF5030A voltage reference. 


The TPS544C20EVM evaluation module (EVM) allows users to evaluate the TPS544C20. The TPS544C20 is a D-CAP2™ mode, 30-A SWIFTTM converter with PMBus TM. It provides a fixed 1.2-V output at up to 30 A from a 12-V input bus.

Fusion Digital Software

TI’s Fusion Digital Power Software is the Graphical User Interface (GUI) used to configure and monitor select Texas Instruments’ digital and analog controllers and sequencer/health monitors. The application uses the PMBus protocol to communicate with the device over serial bus by way of a TI USB adapter. Learn more.


  • Fusion Digital Power Studio: Has software tools for TI’s UCD3138 Integrated Digital Controller family. It assists in the evaluation, development and testing phases of designs.
  • Fusion Digital Power APIs: Is built on top of a Microsoft.NET Application Programming Interface (Fusion-API) and handles I2C/SMBus communication and abstracts devices and commands.
  • Fusion Digital Power Production Tool: Is a GUI used to download firmware, upgrade firmware, configure, calibrate and test. Allows integration of UCD flashing procedures in a production environment.
