Hello to all !
we need to have the diagram with component list for the follow project :
we have 2 signal :
A - 12 V from a switch
B - 12 V power from battery
A,B connected to a DC converter ... our problem is we can't leave powered on the DC converter all the night so we need to shut down after few minutes (15-20 min can be good )
these are the states :
1) starting from shut down system :
A+B ON : pushing a C switch ( we already have this circuit ) the system will start
2A) if the system is ON, I can shut down from switch C, in this case the DC converter will be powered too and we need to shut down after 15-20 min
2B) system in ON, if I turn off the Switch A, system will be on for 15-20 min, then it will power off the dc converter input from battery
ask me if something is not clear

I will be, happy if I can help you. that is simple project ,I can pass schematic for that to [url removed, login to view] we can add time adjustment to that system,thank you
I am currently working on Boost applications as well as buck applications. driving LED lighting applications from 6V & 12V batteries. Can trust me on this.
I have more than 3 years of experience in electronic design and testing. the problem u've defined can be solved usnig microcontroller based circuit.
