SLUUCZ1 July 2024 TPS546C25
The TPS546C25 IC leaves the factory preconfigured. The factory default settings for the parameters are found in the data sheet. Use the software in Test and Configuration Software to configure the EVM to settings other than the factory defaults. Make sure to have the input voltage applied to the EVM before launching the software so that the TPS546C25 is responsive to the GUI and the GUI recognizes 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 4.75V; therefore if necessary to avoid any converter activity during configuration, an input voltage less than 4.75V must be applied. TI recommends an input voltage of 3.3V.
