I have an application where I have a circuit involving a switching regulator. Nothing in the circuit can be modified except the feedback loop.
The output voltage must be adjustable so I was thinking of using an eepot for the application, but the range and the precision that I was getting was nowhere close enough to what I need, so I experimented with current injection, but was told that it is a bad idea...
Does anyone have any suggestions for another way to change the output voltage of a switching regulator?
Thanks!
