I&#39;m wondering if it&#39;s possible to provide 1.3V directly to the DEC4 pin rather than use the internal DC_DC.en-USTelligent Community 13Tue, 05 Jan 2021 09:01:51 GMThttps://devzone.nordicsemi.com/thread/287427?ContentTypeID=1Tue, 05 Jan 2021 09:01:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dd24abd3-f727-4d13-82aa-4cc9f4548eccbrahamb<p>Thanks</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/287275?ContentTypeID=1Mon, 04 Jan 2021 14:06:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ef4fa2ce-bd76-4382-9a48-a564870cf5a6ketiljo<p>No, that&#39;s not possible. There are quite a few power domains other than DEC4 that needs to be supplies from VDD The power on reset circuitry needs VDD to work.&nbsp;</p><div style="clear:both;"></div>
