5.1 Configuration Procedure

  1. Adjust the input supply to provide at least 4.25 V.
  2. Apply the input voltage to the EVM. Refer to Figure 4-3 for connections and test setup.
  3. Launch the Fusion GUI software. If prompted, select GUI scan mode to DEVICE_CODE only. Refer to Figure 5-1 for changing device scanning options. The software will recognize the TPS53819A device on the EVM and load the GUI.
  4. Configure the EVM operating parameters as needed.
CAUTION:

Some parameters can be configured, such as switching frequency, to values that can result in erratic or unexpected behavior on this EVM. Consult the TPS53819A 3-V to 28-V Input, 40-A, Eco-Mode™, D-CAP2™ Synchrons Buck Controller Data Sheet for guidance in configuration of parameters and impact on component selection.
