Jens,
Two things:
1. Make sure you know the maximum voltage on that resistor adjust pin,
and select the control chip accordingly.
2. The control will be non-linear no matter what, so use a lookup table
to convert desired voltage to the resistor switch or digital pot value
or whatever.

Hey David, hey Carl, thanks for your input. I would like to avoid a
resistor approach due to the 1/R characteristic of the output voltage...

Hi folks,
I want to adjust the output voltage of the Taylor Edge HVPS 1363
[1] digitally via a microcontroller. I drive the HVPS with 12V to
have maximum output current.
I know that I could just select the voltage with a couple of
switches and resistors, but is there a way to do that digitally?
Thanks for your input,
Jens

Digital Potentiometer?
Lots of different types depending on what kind of digital interface /
resolution you need.
