5 EVM Configuration Using the Fusion GUI

The TPSM8D6B24 leaves the factory pre-configured. The factory default settings for the parameters can be found in the data sheet. If configuring the EVM to settings other than the factory defaults, use the software described in Section 4.1. Ensure the input voltage is applied to the EVM prior to launching the software so that the TPSM8D6B24 can respond to the GUI and the GUI can recognize the device. The default configuration for the EVM to stop converting is set by the EN/UVLO resistor divider to a nominal input voltage of 3.5 V, therefore, if it is necessary to avoid any converter activity during configuration, apply an input voltage less than 3.5 V. TI recommends an input voltage of 3.3 V.
