I am working on a design where I would like to be able to adjust the output of a power supply remotely. I am thinking of using the LM25119 and placing a summing amplifier between the output of the supply and the FB pin and I would sum in a voltage to change the total output voltage. Will the phase delay through the op-amp cause this to be an unstable solution?
I would like to be able to adjust the output voltage between 1V and 18V, with a maximum output current of 15A.
