Hello fellows!
I need help creating a back up circuit.
Here is my current set-up:
I have 120V -> 12.6V (300 mA) transformer that will power 5V regulator for a microcontroller
It will also power a 12V regulator for a bit higher current device (controlled by microcontroller via a transistor).
Now the backup will consist of 8 REGULAR duracell non-rechargeable batteries that yield 12 volts of power.
Now, the thing is that I have a limit on the components. I only have various resistors, couple of general purpose NPN transistors and a bunch of low voltage 1A diodes.
What circuit design can you suggest? Thanks much in advance!!!
