hello again, my old psu quit and instead of trying to fix it, I decided to build a new one. heres what I need it to do.. Im trying to keep the old carbon fiber case I built for the old board. it has 5 switches and leds so Im stuck at keeping it that way, I need it to have 3.5v,5v,9,12v,15v, and 24v. It has to fit in a 2.5" by 7" area with 3 inches of height.. The old one has shut down with less than 300ma of draw, I would like the new one to be at least 2a.. I want to try to use a lot of the stuff I have laying around to build it and I have a trunk full of salvaged parts. I see a lot of schematics around that use the lm317 as the voltage regulator but the data sheet says its only good up to 1.5a. I have a few of these so can I use 2 of them to get the current up or is there a better solution? I also have a bunch of transformers from small to pretty big. however most of them have no writing at all on them. So how do I find the primary and secondary coils in them and find out what the voltages, amphere of them are? So this is where im at with my project. my skill level is somewhere between beginner and moderate so the easier the better.. thanks
is it the size of the transformer or the capacitors or the diodes on the bridge rectifier that controls the current the most?
