Hi, could you please check if there is anything wrong with this configuration? It feels like it should work from 2V to 5V

Hello,
Sorry for the late reply.
The configuration looks good.
When using the USB peripheral, a 5 V USB supply needs to be provided to the VBUS pin.
The USB peripheral has a dedicated internal voltage regulator for converting the VBUS supply to 3.3 V used by the USB signalling interface (D+ and D- lines, and pull-up on D+). The remainder of the USB peripheral (USBD) is supplied through the main supply like other on-chip features. As a consequence, VBUS and either VDDH or VDD supplies are required for USB peripheral operation.
So yes, it should work for 2V to 5V when high voltage mode and USB is supported.
Thanks.
