2.2.2 Hardware Setup for Single Device

The LP5891EVM can be powered either by the TMS320F280039C LaunchPad with the USB power (when the current consumption is low) or an external power supply (the LP5891EVM and the TMS320F280039C LaunchPad are powered separately). Single LP5891EVM can be quickly set up and tested by following these steps:

  1. USB Power supply from the TMS320F280039C LaunchPad
    1. Download the code to the TMS320F280039C LaunchPad with TI Code Composer Studio software.
    2. Put the J6 jumper on MCU5V and the middle, and set the switch S1 towards SOUTHOST, which are marked with red boxes in Figure 2-3.
    3. Connect BoosterPack connectors (J1, J2) on the LP5891EVM with the TMS320F280039C LaunchPad, the connection method is shown in Figure 2-3.
    4. Power the TMS320F280039C LaunchPad through the USB cable.
  2. External power supply
    1. Download the code to the TMS320F280039C LaunchPad with TI Code Composer Studio software.
    2. Put the J5 jumper on TP1 5V and EX 5V. Then put the J6 jumper on EX5V and the middle. Set the switch S1 towards SOUTHOST.
    3. Connect BoosterPack connectors (J1, J2) on the LP5891EVM with the TMS320F280039C LaunchPad, the connection method is shown in Figure 2-3.
    4. Power the TMS320F280039C LaunchPad through the USB cable.
    5. Connect TP1 and TP2 to 5V/GND power source.
    6. Power on 5V/GND power supply.
