Digital Power Software Development Kit¶
The Digital Power Software Development Kit (DP SDK) is a cohesive set of software infrastructure, tools, and documentation designed to minimize C2000 MCU based digital power system development time targeted for various AC-DC, DC-DC and DC-AC power supply applications. The software includes firmware that runs on C2000 digital power evaluation modules (EVMs) and TI designs (TIDs) which are targeted for solar, telecom, server, electric vehicle chargers and industrial power delivery applications. DigitalPower SDK provides all the needed resources at every stage of development and evaluation in a digital power application.
The DP SDK is built on top of C2000Ware and is available for download from https://www.ti.com/tool/C2000WARE-DIGITALPOWER-SDK. The SDK is also available online via the TI Resource Explorer for C2000 DP SDK.

Libraries¶
The libraries included in Digital Power SDK range from ramp generator and power measurement libraries to specialized software phase lock loop libraries as well as the Software Frequency Response Analyzer (SFRA) library. The libraries directory includes documentation and examples when applicable. Additional information on the libraries is available in these guides:
powerSUITE¶
powerSUITE is a suite of digital power supply design software tools. It helps power supply engineers drastically reduce development time as they design digitally-controlled power supplies based on C2000 MCUs. More information on powerSUITE is available at https://www.ti.com/tool/POWERSUITE.
powerSUITE consists of three tools designed to help engineers more easily traverse through the different design stages of a digital power supply systems. The tools are:
Solution Adapter allows for customization of examples in the DP SDK and for configuration for a custom digital power board design.
Compensation Designer allows the design of different styles of compensators (ex: PID, 2p2z, 3p3z) to achieve the desired closed loop performance.
Software Frequency Response Analyzer (SFRA) enables the measurement of the open loop gain of a closed loop digitally controller power converter using software.
