Power-up Sequence Issues

[LH1]

For the STM32MP135 series, specifically the STPMIC1A I'm using, can VDD_CORE and VDD_CPU share the same power rail (buck1)?

HI @LH1 

you could probably find some answers in following documents:

• AN5587 Integration of STM32MP13x MPU product lines and STPMIC1D / STPMIC1A on a wall adapter supply
  • especially figure 2
• AN6312 How to use STPMIC1L for a wall adapter powered application on STM32MP13x lines MPUs
• AN5586 STM32MP13x MPU product line discrete power supply hardware integration
