Good day,
I would like to know how can I get a regulated voltage of 4.5V out of the DA14680 to power an external device. I am not seeing how to do so in the datasheet/ appnotes provided. From what I see the Buck converter is linked to the VDD, V18, V18P or V14 outputs. However, I am not seeing how can I get such a voltage at any of these outputs.
Thanks in advance.
