Core supply for STM32H573AII3Q

[madhu1]

Hello, We are using STM32H573AII3Q in our application. It has in-built SMPS for core power supply. Just wanted to know can we disable this SMPS and use seperate external 1V LDO to power the core?

Yes, this is possible.

See the hardware design guide for more information on this.
