I was working on web (lol), and i red this st forum post :
about using external smps regulator in place of internal ldo regulator to save energy for STM32H743.
That is right in new stm32h7xx with embedded smps, the consumption is divided by 2 compare to embedded ldo.
Do you have any idea, or roadmap about this ?
It seems to cost an external smps regulator with components and Register to change at start for soft.
