Using the Fusion Digital Power Designer GUI
For optimum performance of the GUI, the PMBus Bus Speed should be set to 400kHz. This parameter is
set in the USB to GPIO pod. To see the current pod settings, go to the System View window
and click on the "Tools" option in the very top menu bar. Select "USB Adapter Settings" from the drop-
down menu that appears. This will display the current settings of the pod. Set the pod to match the
settings shown in

that is directly connected to the host computer. Performance may be degraded if the USB connection is
thru multiple hubs.
Note that when using the Monitor Mode window
windows. These can be changed as desired. The Vout plot also displays the present Vout setting and
allows it to be changed on-the-fly. When a parameter is changed, click the "Write" button in the plot
window to transfer the new value to the module RAM. If a Fault or Warning threshold is changed to a new
value and the module is presently exceeding that new value, a Fault or Warning condition will be asserted
as soon as the new value is stored to RAM.
When exploring the GUI, there are many settings displayed that can be altered. Great care should be
exercised before altering any setting whose function is not obvious to the user. Altering certain settings
could allow the module to operate outside of its design limits and potentially cause damage to the device.
Remember that the "Store Config to NVM" button permanently stores any changes made to settings that
have NVM backup. The factory settings cannot be recalled once they are overwritten.
