This could be run as a dual supply in the same way the TREAD could be run as one:

Looks like I blew the build, guys.

   I got R6 and R7 correct, but I neglected to order the correct versions for D1 and U2 at 24V output.  I can't get any more than ~8.6VDC on the output and I don't have a load that low to test.
 
I'll have the right parts on order today.

What ever happened to this project?

Umm ... unfortunately, it's in my lap.  I built one for the purpose of making specific measurements using Tangent's LNMP.  However, my LNMP batteries shorted out, made a mess and blew up the TLE chip.  Dsavitsk fixed it for me, since I was pretty busy at the time, but then I blew out the r1 I built.  (I put too much voltage and current load on it.)  I have all the parts to build a new one, but just haven't got 'round to it, yet.

Does this mean you now know what maximum voltage and current it can feed? I'd be interested in those numbers.

Just going from memory, but I think cobaltmute indicated that there's no problem exceeding what I did - it's just that the parts selection at present was not set up for that much.

I have a few projects that would benefit from a board like this. I'm thinking of going with a Salas v1.1 BiB which might be overkill. Or a Sigma 25, which might be in the same league. I like that the size is super small and flexible.

yeah me too.  I have a dynalo I need to  recase and it just needs a reg like this

I'll admit to not having looked at the circuit in quite a while so it would take me a few moments to figure out the limits with the "default" BOM we spec'ed. That doesn't mean that you can't spec out a different set of parts to meet a specific need. With the proper choices for parts (and heat-sinking), the practical limit will be the copper traces on the board.

What a fascinating thread. I just read through the whole thing. I probably understood 2% of it, but it was great to see how the project developed. It's too bad it's been languishing a bit, however...
 
Question: would it be feasible to build several of these to use as bench power supplies? Maybe a 3V, a 5V, a 6V and a 12V? Other than continually adjustable voltage, what would the benefit of a bench power supply be?
 
Best regards,
Adam

Is this project officially dead? I'm looking for a small, low-cost 6.3V power supply and I thought this might be perfect, but...

No, it's not dead - just in suspended animation because of me.  I'll try to do better.

 

[amcananey]

Not trying to pressure anyone - you don't owe me anything and if this ever comes to fruition, I'll be grateful for the work you and everyone else has done. Thanks for the update -- glad to hear it isn't dead!

Any progress?

Sorry for the thread revival. Any updates after all this time?
