14 Monitoring, Re-configuring and Re-tuning with Designer GUI
In this section, we describe how to use the Designer GUI to evaluate the single-phase PFC board,
UCD3138PFCEVM-026
14.1 Power On and Test Procedure
Power stage connection is the same as described earlier. Additionally to that setup, PMBus connection is
required through USB-to-GPIO as shown in Figure 44.
After all connections are made, apply an AC source voltage with a specified value to the board AC input
and refer to the other steps in the UCD3138PFCEVM-026 user’s guide. Open and start the “Fusion Digital
Power Designer” GUI following the steps described in Section 13.2 and Section 13.3. Once PFC pre-
regulator is up and running and the GUI is opened, then it is ready to use the Designer GUI to make
evaluation.
