Hi, I want to power an existing LED array from a wall-wart type adapter. I designed the array for use with 6v lead acid batteries, which are usually around 6.7V fully charged. Is there any good info on how I can design a regulator to get a smooth and constant supply from the nasty, lumpy general purpose wall-warts? I know a 6V adapter can be as few volts out in either direction, and they fluctuate a lot, which is not good for LEDs.
Where can I find detailed info on how to design a regulator circuit to build into the array?
I've seen self-contained voltage regulators, but I have never used them, and don't know anything about them. Would I have to do any designing? Does it matter how far above/below the desired output voltage the input is? I'd assume it does, but how much? And what if the input can vary quite a bit?
As long as the wall wart can easily provide the current required by the array, is this an easy thing to design? Where can I find the maths?
I'm sure there are units that already have built-in regulation, but I'd like to learn more about this for other projects, plus I like the idea of being able to easily find replacement supplies in any hardware store.
