I'm designing a custom PCB with STM32U545NEY6Q and I don't need to use the SMPS, only the LDO. I'm not sure how to connect the SMPS, I found a post about the STM32H745IIT6, and followed the same procedure, but should I do that?
I followed the datasheet recommendations and connected the pins as shown in the image below.
I didn't find a similar version of the MCU without the SMPS, and the MCU dimensions fit my design perfectly. Can you tell me if this connection will work? Or recommend another similar MCU, from the STM32U5 series, without SMPS?
