Dc-DC design help
Is there a possible way of getting a variable voltage output with a constant input voltage?
I want to supply 12V and get out 0-12V at approximately 1A. Il be using a current shunt so that I can provide a constant current. Im planning on using a 100mohm resistor outputting 0-100mV, then inputting that into a op-amp and using this voltage as a feed back voltage.
The whole thing will be used to charge a bank of ultracapacitors at a constant current, currently ive been trying a mc34063, but its not working out.
Thanks,
Andrew
