Hi,
I would like the DC/DC converter of STKNX to make 5V.
Also, I want the Linear regulator to make 3.3V
Because of global efficiency, I wanted to power the linear regulator with the 5V output of DC/DC converter.
I'm surprised that the datasheet specifies VDD_REGIN minimum voltage 6.8V, if VCC_SEL is shorted to ground (in order to make 3.3V linear regulator output).
Same for VDD_REGIN minimum voltage specified 8.5V, if VCC_SEL is shorted to VCC_Core (in order to make 5V linear regulator output).
This makes 3.5V voltage dropout, which seems pretty much to me.
Question: Is there a typography error in Datasheet? Or is the dropout of internal regulator as much as 3.5V ?
Many thanks,
Alexandre
