3.1 EVM Configuration Using the Fusion GUI
The TPS546C25 IC leaves the factory preconfigured. The factory default settings for the parameters are found
in the data sheet. Use the software in
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.
3.1.1 Configuration Procedure
1. Adjust the input supply to provide 3.3VDC with the current limited to 1A.
2. Apply the input voltage to the EVM. See
3. Launch the Fusion GUI software. See the screen shots in
4. Configure the EVM operating parameters as desired.
By default, the resistors on MSEL1 and MSEL2 configure U1 single phase converter.
3.2 Using the Fusion GUI
3.2.1 Opening the Fusion GUI
The Fusion GUI must include the IC_DEVICE_ID in the scanning mode to find the TPS546C25. The EVM needs
power to be recognized by the Fusion GUI. See
section use screen shots showing other TPS546C25 family devices to illustrate the use of the FUSION GUI with
the TPS546C25EVM-1PH when those functions are similar.
