Hi,

This information can be found in section 7 of the Product Specification.

The supply voltage range for DC/DC mode is 2.1 V to 3.6 V.

Best regards,

Hi,

Ah, sorry for the confusion. There are several output voltages, however these are not suited for powering external devices. You can find figures of this in the Reference Manual, for example in section 12.1.2. Some of the voltages are 1V2 and 1V7. The AVDD voltage is between 0 and 1.8V, please see this post.

Best regards,

Øyvind
