Using STM32WLE5 sub-GHz in high-power mode (22 dBm) with internal LDO

[viola]

Hi,

I just want to make sure that it is possible Using STM32WLE5 SUBGHZ IN HIGH-POWER MODE (22 DBM) , higher frequency band , WITH THE INTERNAL LDO  ?   (without the internal SMPS )

I am asking because i see in the CUBE-MX under the tools tab that there is no option to select "high-power" when selecting "SMPS OFF" 

Thank You,

Viola

Hello @viola 

As you can see on the chapter 4.3.3 of the RM0461, the transmitter for high output power does not need SMPS to be configured :

 For the CubeMX part, can you please give more details (how to reproduce).

Best Regards.
