The TPS2391EVM is an evaluation and demonstration board and kit tailored for the Texas Instruments TPS2391 PDM Bridge and USB Hub Controller. It provides a complete platform for evaluation and design of systems incorporating the TPS2391. The EVM includes a USB host upstream port, an integrated Type-C connector port, a USB Downstream 0 port, and an Adaptive USB Power Switching (AUPS™) port.

The TPS2391EVM has a programmable power supply with adjustable voltage and current limiting capability, and the EVM is designed for easy user evaluation of the TPS2391. It also features an easy port for programming the CPLD that governs the Bridge/Hub configuration. The board provides the following features and tools:

• On-board USB-C connector for direct connection to a PC or device
• Integrated Flash programmer for programming the CPLD
• Two channel programmable power supply
• Programmable timers for system activity and performance evaluation
• On-board function/feature checking circuitry for evaluation and debugging
• A complete library of example code, schematic/wiring diagrams, and user-guide PDFs

The TPS2391EVM is primarily designed as an evaluation and demonstration tool for the TPS2391. It can be used to evaluate the performance of the device, measure device performance under different conditions, and helps users quickly understand and confirm the functionality of the Bridge and Hub Controller. Additionally, the EVM can also serve as a development board and users can build their own development systems with it.

The TPS2391 EVM board is powered by an external wall adapter or host connected via USB. The voltage and current levels are adjustable via the programmable power supply. There is also an external USB-C connector on the board, providing convenient connections with the PC for data communication or power delivery. The power supply of the EVM is highlighted by a flashing LED indicator, allowing users to identify whether or not the power supply is correctly connected.

The TPS2391 EVM board comes with a complete library of example code, schematic/wiring diagrams, and user-guide PDFs that provide necessary information for board functions and usage. The software library is highly versatile and reflective of the TPS2391’s capability. The software library contains all necessary functions to test and evaluate various features such as 1-level and 2-level ports, port sharing, and power distribution for various connected peripherals.

The on-board CPLD programmed by the flash programmer can be used for sophisticated project design. It is also not very difficult to debug the project and check for errors, since the on-board function/feature checking circuitry is present. Furthermore, the board also comes with two channel programmable power supply and programmable timers for system activity and performance evaluation, enabling users to perform meaningful tests and get accurate results in different working conditions.

In summary, the TPS2391EVM evaluation and demonstration board and kit is a powerful and versatile tool when it comes to evaluating the TPS2391 bridge and hub controller. It provides all the necessary features and tools to quickly understand and confirm the functionality of the device. Additionally, the board offers a complete library of example code, schematic/wiring diagrams, and user-guide PDFs, together with two channel programmable power supply and programmable timers for system activity and performance evaluation. This makes the TPS2391EVM the perfect choice for evaluation, demonstration, and development applications.
