Electronics help!!!
« on: July 29, 2007, 03:33:50 PM »
Hey guys...

Basicly I'm in dire need of a step down solution. I have 24v@4A max coming from a FET and I need to step it down to 5v so I can use it to power RBG LED's in parallel. I've been looking at NPN driven dc/dc tranformers, Line regulators, and standard volage regulators like the LM78xx which can handle the 24v input. We're building 12 of these LED controlers for an art project, and each controler has 3 channels! So if anyone can help me with a informed solution, I would be greatly apreciative.

Here is the controller we're using. (common anode)

So this way we can also cut down on the overall LED's required.

Our deadline is next month, and if we don't solve this problem its a lot of wire and frustration putting out a full 24v@4a in to series/parrallel design.

Thanks in advance,
~Dingus Mungus

Scratch that!
We're going 6v golf cart cells and using resistors to pull down each channel.
