The Fusion Digital Power Designer software has a convenient graphical interface to configure and test TI VR13 controllers.

An more detailed discussion of each parameter in the GUI can be found in the application report Using the Fusion Digital Power Designer for TPS536xx VR13 Multiphase Solutions. Contact vr@list.ti.com for more information.

  1. Connect the USB-GPIO adapter to either a system board, or socketed programming board with a TI VR13 controller on-board.
  2. Apply 3.3 V to the V3P3 pins of the controller devices. It is not necessary to apply 5-V and 12-V power. Make sure to disable power conversion. You may need to pull the AVR_EN/BEN pins low to stop power conversion.
  3. Start the Fusion Digital Power Designer software.
  4. Click Change Scanning Modes, then select DEVICE_ID & DEVICE_CODE & IC_DEVICE_ID if the software does not recognize your device.
