High current digital pot?

[Atom058]

Hello All! Thanks so much for your replies! For some reason, I did not get any notifications of your responses like I used to get - I guess there's a new flag that I need to set on my account to notify me of responses... I think I have solved my problem - It was a combination of the RC filter and upping my frequency. I am still tinkering with it and will post my results soon. Very encouraging so far! Thanks again! It never ceases to amaze me the tremendous knowledge that is available here in this forum!

If it is useful, I have a ckt that will give NEARLY pure DC (100mV p-p ripple) from 0-47V (with 48V in), or 0-11.5V (with 12V in) at up to 20 Amps. It doesn't generate
much heat, either. Of course, it uses PWM.
