2.2 Setup

Out of the box, the TPS26750AEVM evaluation module is configured for a default configuration of 15W (5V/3A) source and 100W (20V/5A) sink power. When different configurations are required, use the application customization tool to create a configuration or load a different configuration template. Refer to the GUI user guide for detailed instructions on using the application customization tool.

To use the device in a standalone operation, connect either of the following:

  • A USB-PD power supply with a minimum wattage capability of 45W to J7
  • An external power supply of up to 48V to the VSYS screw terminal (J5)

The device can also act in dead battery mode by connecting a USB Type-C® cable to J1.

To connect the BQ25756EVM evaluation module to the device, the interposer board provided must be connected in between the TPS26750AEVM and BQ25756EVM evaluation modules. An example of how to connect the two boards together can be seen in Figure 2-1.

Follow the instructions to connect the two boards:

  1. Unscrew the terminal screws on J1 and J3 of the BQ25756EVM evaluation module.
  2. Insert the interposer board taking care to fully insert the leads before screwing down the terminals.
  3. Line up the interposer board with the TPS26750AEVM evaluation module.
  4. Push the contacts into place until the contacts make a secure connection.
    Note: The boards are on slightly different vertical planes.

  5. Attach one side of the provided ribbon cable to J8 of the BQ25756EVM evaluation module.
  6. Attach the other side of the provided ribbon cable to J3 of the TPS26750AEVM evaluation module.
    Note: Pins 1 and 2 of the J3 connection point on the TPS26750AEVM evaluation module (the pins closest to the drill hole of the board) are not connected to the ribbon cable.

Note: The figure uses a different revision of the TPS26750AEVM evaluation module, with slightly different net names; however, the electrical connections are identical.
