Fusion Digital Power Graphical User Interface (GUI)
When using the UCD92x0 digital controller along with digital PowerTrain modules to design a digital power
system, several internal parameters of the modules are required to run the Fusion Digital Power Designer GUI.
See the plant parameters below for the PTD08A210W digital PowerTrain modules.

Internal output capacitance is present on the digital PowerTrain modules themselves. When using the GUI
interface this capacitance information must be included along with any additional external capacitance. See the
capacitor parameters below for the PTD08A210W digital PowerTrain modules.
