I found that the STM32WB55 microcontroller have SMPS but I cannot understand how much external component is required.
Here is basic SMPS circut and could you tell me how much circuit is in the microcontrollers SMPS?

In addition, can I directly apply AC current to the microcontroller's SMPS to get DC current?

I read AN5246 but still I'm not sure whether I can use random AC signal as a power supply to the STM32WB microcontroller.
if it is possible, Should I connect AC+ to the VDDSMPS and AC- to the VFBSMPS?

Regret to hear this. if the microcontroller has an internal AC-DC converter, I would not need any extra IC components anymore. Sad.
