I don't use the internal Step Down regulator. How should the pins be tied?
Should VDDSMPS be tied to VDD and VSSSMPS to GND with VLXSMPS and VFBSMPS left open?
OR - should they ALL be left open?
Documentation only speaks as if they are to be used - no comments on what to do if not used.
Solved! Go to Solution.

This app note for STM32H7A/B shows them as grounded/floating. Can't imagine it's different for the H745.
