voltage regulators in series or paralle

Did you click on the website I linked in my previous post?

No but I noticed it had romanblack in the URL. I was just wondering if you were calling it a black regulator because Roman Black designed it, or if there really was a TYPE of regulator called a black regulator (which I was unaware of). My question is answered now though, thanks

It does not provide enough current, I need 2.5A 12v regulated, this is not just for a LED array, there are other circuits too.

Then why didn't you say so before? It just looked like you wanted to power nine LEDs using an efficient constant current mode SMPs.

I will prob add a small current limiter just for the led array.

It probably wouldn't take a genius to redesign it to supply more current. All you need to do is change a few component values and beef up the transistors a bit.

Failing that, you could consider a switching regulator IC like the MAX649 or the LM2593.

You must have quite the solar panel if you hope to get 2.5A @ > 14V from it. (assuming you want to regulate it to 12V)

National Semiconductor makes "Simple Switchers" ICs, many can pass 3A to 5A.

That is peak usage with some overhead should I add extra circuits and possibly another panel if required. I currently have a 12v 15w panel 1.25A in good conditions

Well I did in prev posts. Recommendations changed the design from the initial post.

The is prob true, but I have little idea what I'm doing, lets say I am ambitious.

I am doing, that is why I said I would start a new post as this one was going off topic and the original question.
