7 TPS92682EVM-125 Power UP and Operation

To start the EVM operation, connect the header J10 on TPS92682EVM-125 to the header J2/J4 on the LaunchPad, and the header J11 to the header J1/J3, using two included ribbon cables as shown in Figure 7-1.

GUID-20200903-CA0I-PTDC-J4TS-0PDNXMCK6Z65-low.gif Figure 7-1 LaunchPad Connection to TPS92682EVM-125

Apply power (12 V) to the TPS92682EVM-125 board (terminal J1). Connect a resistive or a an electronic current sink load to the output of channel-1, terminal J2. Connect LED loads to the output of channel-2, terminal J5. Ensure that the loads are such that the maximum input and output current, maximum output power and maximum output voltage indicated on the EVM are not exceeded.

Run the program LED_Controller_GUI_LP.exe, located at the ":\Texas Instruments\TPS92682 LaunchPad Evaluation Software", to start the GUI. The window shown in Figure 7-2 opens.

The main GUI window appears as shown in Figure 7-5. This window includes three sub-windows:

  • MCU Control Box (1): includes controls for external PWM
  • SPI Command Box (2): is used to manually read from and write to the registers on the SPI BUS
  • Devices Box (3): is the main GUI control window to configure the TPS92682-Q1 device
