Hello, I am Using UCD3138PSFBEVM-027 and Fusion Digital Power Studio.

I have loaded it 1A and 30A, but the output voltage on Fusion Digital Power Studio is giving erroneous output voltage.

1A load

30A load

Where to find tutorial videos of Fusion Digital Power Studio?

Hi Victor,

Thank you for choosing the UCD3138x products. Because your output is regulating correctly, the UCD3138x should be ok. Instead, the issue is likely the Fusion GUI. We have had some issues of using the USB-TO-GPIO2 (2022) adapter with the Fusion GUI displaying incorrect information.

Here is a new Fusion GUI that you can try: https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/196/0284.TI_2D00_Fusion_2D00_Digital_2D00_Power_2D00_Studio_2D00_3.0.83.test I changed the file extension to ".test" since executable files are blocked. Just rename the extension as ".exe" to install.

You can also see this E2E post for PSFB bringup: https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1541111/ucd3138cc64evm-030-psfb-cannot-configure-board-change-frequency-or-see-any-dpwm-outputs/5969682?tisearch=e2e-sitesearch&keymatch=%252520user%25253A525510#
