Hi all. I have a laptop power supply giving 12V, 5A out. I wish to split this into 4 tunable outputs with these specs:
out1 & out2 : 9-12 V, with a bypass switch on both to get the 12V 5A out directly. Shared current available 2,5 A, when not bypassed.
out3 & out4 : 3-5 V. Shared current available 2,5 A.
I know how I could build this with LM317 or similar components. But I'm not sure if it's the best way to do it. How would I do this with the least amount of components and being reasonably power efficient so I dont need active cooling?
