Please follow the steps below precisely to quickly evaluate the TPS389C03-Q1. In this quick start, the TPS389C0XEVM is set up to monitor several power supply rails.

1. Make the hardware connections and software installation described in Section 3.1 have been completed. Feel free to skip the GUI installation if the Fusion Digital Power Designer for TPS389C0XEVM GUI has been installed already.
2. Power the EVM by turning on the power supply. Note that the voltage and current limits at the power supply is set at 3.3 V and 10 mA.
3. Once the TI's USB2GPIO USB Interface Adapter is connected to EVM and the laptop, launch the evaluation software Fusion Digital Power Designer.
4. Click on I2C GUI on the bottom right of GUI.
