Evaluation and demonstration boards and kits facilitate the testing and evaluation of microcontrollers and other components used in the development and design of electronics projects. The Texas Instruments TPS65281EVM is an evaluation module specifically designed to demonstrate and evaluate TPS65281 control integrated circuit (IC). The application field and working principle of the TPS65281EVM board are outlined in this paper.

The TPS65281EVM board is designed to evaluate the features and performance of the TPS65281 control IC in automotive, industrial, and general-purpose applications. The IC itself is designed to control power for 1.4–1.5V rail systems and incorporates low-power and low-current features. The board is evaluated with two input stages, a buck stage and an inverting buck-boost stage. The buck stage can be operated in step-down, synchronous buck, step-up, or inverting buck-boost modes, with selectable output voltage ranges of 0.8V to 5.5V, and an adjustable output voltage precision from ±1%.

The TPS65281EVM board supplies power to an external load or peripheral device from the integrated IC. The board also includes a power switch control circuit and an internal temperature monitor circuit, both of which are connected to the TPS65281 IC. In addition, external components and circuit elements can also be connected to the board for the evaluation of the IC’s features and performance.

The TPS65281EVM board can be programmed and configured for various test and evaluation scenarios using a Windows-based GUI. The software provided with the board enables users to program the IC, set up the board, and record data. The software also includes a temperature monitor that provides visual feedback regarding the status of the board. In addition, the software allows for the measurement of current, voltages, and other parameters.

The graphical user interface (GUI) also provides access to various settings and configuration files. The board’s settings can be modified through the GUI, including the configuration of switching frequencies and output voltage levels. Evaluation of the board can also be done using the GUI, including the monitoring of input and output voltages and currents, and the measurement of power delivered. All data collected can be stored and documented for future reference or to be shared with other engineers or designers.

The TPS65281EVM board has the following features: a power-switch control circuit connected to the TPS65281 IC, an internal temperature monitor, and the ability to connect external components and circuits for further testing. The board can be configured using a Windows-based GUI for various evaluation scenarios, and the data collected can be stored, analyzed, and documented for future use. The board is designed to help designers and engineers evaluate the performance of the TPS65281 control IC in automotive, industrial, and general-purpose applications.
