Disable internal SMPS by Harware STM32H755IIT

Kura
Associate II

Well I tried to read the documentation, but found only HW requirements to use SMPS. So is the SMPS required?

Or can the SMPS just tie VDDSMPS, VLXSMPS, VFBSMPS and VSSSMPS to ground directly on PCB when no needs for that?

You are not required to use SMPS. The power supply options and how to connect pins in each case are outlined in the reference manual.
