I Need a Magnetics Designer(vanity)

I have a challenging magnetics (transformer) problem that I am looking for help with. Basically I need components for an unusual power supply. The PC boards are already done, but can be reworked to match your design if necessary. This is not a charitable contribution, and anyone who can solve it will be rewarded. Please either respond to this thread or FReepmail me if interested in hearing more. Thank you.

Not a lot to go on.

I can’t tell if you need an electromagnet, a transformer or a power supply to drive something you already have.

This isn’t one of those minimum information problems like the guy who rides the elevator all the way down every morning, but only halfway back up in the afternoon, is it?

Sorry for the lack of details. I need a power supply to power an existing gadget that has great market potential. The power supply I came up with had a fatal flaw in the voltage step-up design. The IOs are done and work fine. I can FReepmail you more details if you like.

At least give us the voltage, current and the frequency...

How soon do you need this fixed?

I know the best in the biz, unfortunately he is in the hospital recovering from a heart attack so it would be a couple of weeks...at least

FReepmail away.

Nothing sounds scary yet.

It's John McCain! He can't lift his arms above shoulder level - and he's still in that penthouse in the clouds...

Have you looked at the simple switcher?

Yep, I’m going gulch if I can get this thing working.

I’m a switching power supply designer with over 15 years experience. Freepmail me, and I will send resume.

Here’s something that’s making the circuit. /rimshot

Aye.

BTW, I still plan to mail that disk. What’s it been, four years? :’)

At least.
