Using STM32CubeMX Version 6.11.1 for code generation of STM32U545RETxQ LQFP64.

When pressing "Generate Code" there is a message recommending SMPS setting from the PWR menu.

However, no SMPS there and not anywhere in the configuration menu. (Attached)

Any idea?

STM32U5 series

Hello @IP.2

To configure the SMPS you need to go to: Power and Thermal>PWR>Low Power and check the box Power Saving mode. After that, on the configuration tab go to Power Saving>System power supply and you can configure the Power Regulator to LDO or SMPS:

PS: Make sure to use the last version of the STM32CubeMX (V6.13.0).

Best Regards.
