I ran across a website somewhere that had a schematic for a simple low part count buck regulator. The regulator could be configured as constant current or constant voltage.

It was a site of one person and not one of the those sites where people just post projects.

The owner of the site / designer of the project described it as new, something he recently finished (if memory servers).

The site was fairly well laid out with design options for the buck regulator. He had a few other projects posted too but the site was not overwhelmed with projects.

I think I ran across it on AAC but not sure. Anyway I forgot to bookmark it.

Is anyone aware of the site I am describing?

 

Were you looking at one that used an IC controller, or all discrete components?

IC Controllers have as few as 4 parts total, including the IC.

Here is a Page on Theory of SMPS with formulas, no complete schematics, but it's a good place to get general knowledge on DC-DC converters.

Like I said. This one used discreet components. I was looking for that specific site.

That's the one! Thanks!


But I guess it is really a Black Regulator.
