I am trying us STM32H745XI controller in my design, I want some clarification in the power supply section. In Reference manual en.DM00176879->section 7.Power control (PWR) ->Figure22->4.External SMPS Supply, Supplies LDO. I am not understanding how the external SMPS output which connects with internal SMPS output. Please clarify is it connects to Internal SMPS output or Direct External SMPS output connects to the LDO and Vcore.
I am attaching the section which i have doubt and reference manual which i am referring to
Thank you
