2.2.1 Connection with TPS55288

The TPS25752AEVM has the ability to connect with the TPS55288 36V, 16A buck-boost converter with PPS control. Connections can be done either with the generic TPS55288EVM-045 evaluation board or with a USB-PD specific connector board that is made to interface directly with the TPS25752AEVM.

When connecting to the generic TPS55288EVM-045 evaluation board, the following signal connections and jumper configurations must be made:

  • VOUT of TPS55288EVM-045 (J3) connected to VSYS of the TPS25752AEVM (J11)
  • SDA/SCL signals of TPS55288EVM-045 (pin 2 of J5 and J6) connected to I2Cc_SDA and I2Cc_SCL of the TPS25752AEVM
    • Note on earlier revisions of the TPS25752AEVM the I2Cc_SDA and I2Cc_SCL pins are mislabeled on the silk screen. On the earlier revisions of the board (denoted by a white PCB color), the I2Cc_SDA signal marked on the board is actually I2Cc_SCL and the I2Cc_IRQ signal marked on the board is actually I2Cc_SCL.
  • Connection of the reference GND signals between boards
  • Connection of an appropriate external voltage supply to VIN (J1) of the TPS55288-045 EVM
  • The enable jumper (JP1) of the TPS55288EVM-045 must be set to the EN position
  • The slave address of the TPS55288 must be set to 0x74 in the USBPD Application Customization Tool as the MODE resistor on the TPS55288EVM-045 hard codes this address to 0x74

Also note that system power must also be provided either through the USB-PD power port (Conn_2) or through an external power supply on VPWR (J11) to ensure the TPS25752A is provided sufficient system power for operation. A 65W capable PD controller is required on the Conn_2 USB connector or a 20V potential is required on VPWR to provide adequate power. An example connection using the TPS25752AEVM and the TPS55288EVM-045 can be seen below in Figure 2-1:

Alternatively, a dedicated board exists that connects directly to the external board interface connectors on the TPS25752AEVM (J12, J13, and J14). This board can be obtained by reaching out to the relevant TI support team and reduces the number of external wires required for connecting the TPS55288 to the TPS25752AEVM. An example connection can be seen below in Figure 2-2:

Note that in this setup the slave address for the TPS55288 is configured to 0x75 and must be reflected correctly in the application configuration of the TPS25752A that is generated with the USBPD Application Customization Tool.
