oh yes... I didn't saw that... the top resistor is attached to the drain and as opposed to constant resistance circuits that the top resistor is attached to a fixed voltage. wow..

I'll do some mathematical computations for that configuration to be able for me to adjust my design for both CC and CR mode...

thanks a lot!!!

Hello Diver300,

I verified and it worked.



thanks for all those who replied. I appreciated it so much!

I'm glad to be of assistance.

I noticed that your divider has a ratio of 50% so the circuit effectively doubles the resistance of the physical load resistor.

I would suggest a much bigger ratio, so that less power is dissipated in the resistor and you have a wider range of adjustment. You can't go to less than the physical load resistor in any case.
