Hi, I am new here just posted my introduction. I hope this is the correct place to ask this but I am struggling to figure out the best way to supply power to some LED's on a project that I am working on.
So I have four 5v high intensity LED's that need 2.1 amps total (according to my variable power supply). Unfortunately my control board doesn't supply high enough current, So to actually turn the LED's on or off I am going to use a relay or a transitor... probably the relay as I have a spare laying around. My problem is how to supply the power for the LED's. The control board is powered by a 12v source like a car outlet.
I initially thought about using one of my L7805CV transitors to get 5v but they only output 1.5 amps and peak 2.2 amps. Then I though about using a small converter. And that did even worse... I can get 5v but only 0.5 amps out of a 12v source.
I really don't want to have to buy a 5v 2.1 amp power supply if I can help it. Is there a circuit that I can create or some other alternative. Or do I even need to supply the LED's with the full 2.1 amps they drew from my power supply during testing?
