SLUUD52 August 2024 TPS544E27
The TPS544E27 leaves the factory pre-configured. The factory default settings for the parameters can be found in the data sheet. If configuring the EVM setting to other than the factory defaults, use the software PMBus Fusion GUI. Verify the input voltage is applied to the EVM prior to launching the software so that the TPS544E27 can response to the GUI and the GUI can recognize the device. The default configuration for the EVM to stop converting is set by EN resistor divider to a nominal input voltage of 4.6V, therefore, avoiding any converter activity during configuration is necessary. Apply an input voltage less than 4.6V. TI recommends an input voltage of 3.3V.
Some of the tasks you can perform with the GUI include:
After clicking Write to Hardware to make changes to one or more configurable parameters, the changes can be committed to nonvolatile memory by clicking Store to NVM.
