If it is desired to configure the EVM to settings other than the factory settings shown in Table 3, the TI
Fusion Digital Power Designer software can be used for reconfiguration. It is necessary to have input
voltage applied to the EVM prior to launching the software so that the TPS549D22 installed is active and
able to respond to the GUI and the GUI can recognize the device.
