I need a CV CC circuit with the load grounded. I had been using an LM317 circuit with success but that had the current sense resistor below the load causing problems with other parts of the project.
So I have connected 2 simple circuits to make a CV and CC source as per the picture. I would like to combine the voltage ref and current feedback into one transistor but have had no luck locating some examples.
Any advise on helping to temperature stabilize the zener (swap zener with TLC431?), rationalising the circuit to one transistor or examples would be most welcome.
Thanks
