What I am trying to do - I have a dc-dc converter with potentiometer attached to it. I found a couple of digital potentiometers and played around it and go it working. But the issue is, the digital pot, is upto 5v, and my dc-dc converter goes from 12-50V.

so my question is, is there any other way to control the dc-dc converter, by removing the pot present on it and adding a digital control using micro controller?

I was considering adding a motor and 3d print an attachment so fit the pot, and control it. But that might not be accurate.
I have searched and found the max digipot is 36V. Does anyone know any digipot for 40V or 50V or how to create one?


Any help will be appreciated.

Thank you

 

Maybe you could use the switched capacitor technique but I don't know how that would interact with the switching of the converter.

Can't you use a voltage-divider to bring the voltage applied to the pot down to 5V max?
