5 EVM Configuration Using the Fusion GUI

In order to configure the TPS53819A controller on the EVM from its default values, it is required to use the TI Fusion Digital Power Designer software. It is necessary to have input voltage applied to the EVM prior to launching the software so the TPS53819A can respond to the GUI and the GUI can recognize the TPS53819A. At least 4.25 V must be applied to the VDD pin to overcome the default UVLO setting.
