2 Get Started

  1. Download and unzip the TPS274C65 Configurator for Windows
  2. Plug in a power supply (the TPS274C65 supports 12V to 36V nominal) to the VS (J3) banana jack and connect ground to the GND terminal (J8)
  3. Connect relevant loads and ground connections to the output terminals of the TPS274C65USBEVM
  4. Connect the TPS274C65USBEVM via USB to host computer
  5. Open the TPS274C65 Configurator and use the program as described in this guide

The TPS274C65USBEVM requires a standard USB connection to a host computer for interaction between the host software and the embedded firmware running on the TM4C123 microcontroller. The interface is written using standard Windows HID libraries so no driver installation is needed. Besides powering the microcontroller and relevant digital components, the USB power is isolated from the high-side switch and high-current components via the ISO7763DWR reinforced digital isolation.

Please refer to the TPS274C65 datasheet for the exact power supply requirements for proper operation of the TPS274C65 high-side switches. While the high-side switches will protect against over-current events and thermal faults, over voltage conditions outside what the TPS274C65 was designed for could potentially cause damage and should not be applied to the board.
