"SMALLEST, 3V INPUT, 1MHz, 92% EFFICIENT DC-DC STEP-DOWN DELIVERS 10A"


So these are not off-line SMPS, but so what? They're still switchmode
power supplies by definition. TI and several others have similar parts.
It is very likely you have one right in front of you supplying the core
voltage to the CPU in your computer.

That is so cool, I still haven't come across one yet, that I know
of. Now I know what to look for. I'll have to look at the motherboards
of several of my computers. According to the date of the article,
the things have been around for a while.

My statement still stands. I've never seen a switching regulator
that ran at 1Mhz. Just because the chip is capable of 1Mhz does
not mean that that is the switching speed of the regulator. Most
of the design engineers I'm familiar with tend to be conservative.
Your opinion is not that important. Opinions are like tailpipes,
everyone has one, except for those like you who have theirs transposed
with their induction system. FLNF

While I don't condone is attitude, he is absolutely correct. MHz
switchers are common, have been in the field for years, and by the
demands for miniaturization are getting more common all the time. If you
don't believe me, pop open your PC, cell phone, PDA, etc and put a scope
on one of the DC-DC converters. Also with many of these chips, the
switching frequency is fixed and is not something the engineer has a
choice of. The duty cycle varies to regulate the output.

This is not something you'll find in the line operated power supply, but
applications like CPU core voltage which may have to supply less than 2V
at 50-80+ Amps (no, that's not a typo) from a 12V source where board
space is a valuable commodity, or applications needing extreme
miniaturization demand this sort of thing.

Oh my God, a professional actinic sphincter.

What you have your mop out? Looking for work?

I was wrong, you and DimBulb are made for each other.

Kid, I can guarantee that if you and I entered the same industrial
site, I would be able to handle more of the systems than you could.

Thanks, I just looked at the products available from:

http://www.maxim-ic.com/

I've used their other products for years but I was not aware
of their switching regulator chips. The original discussion
concerned "SIMPLE" DC power supplies and some jerk chimed in
calling everyone stupid, etc.

Only because you (and DimBulb) *ARE* stupid, stupid.

BTW stupid, you don't get much simpler than a (part of a) chip,
inductor, capacitor, and two resistors.
My experience has been with the
switching power supplies in computers and test gear which is
what I thought the discussion was about.

Stupid, Sweet just said they're used in the core supplies of PCs.
Though I suppose actually reading what people write is a bit beyond
you.
I've never seen one
of those running at 1Mhz or more. A tiny regulator on a card
or motherboard running at 1Mhz or more is something new to me.
Heck, I learn something new everyday.

Engage brain before mouth, stupid.

The chip we used was also capable of switching faster. Again, that
does NOT mean that a designer is going to operate at the max frequency
capability of a chip he is using... EVER!

Get a fucking clue!

YES WE SEE

YOU WEAR THE GOD DANGED CHIP ON YOUR SHOULDER NOW

FAGGOT GET A LIFE OR LEAVE THIS ONE TO THOSE THAT CAN COPE

I AM PROTEUS

I sure hope they kill your account soon.

And when they do kill your account, which they will... I hope they
also kill the ability for your IP address to load up another account so
that you can abuse this group. You see... I will stop your pathetic
abuse... one way or the other, boy.

I'm assuming that running your design at a lower frequency would require
less RFI shielding. I've seen some designs that put out so much noise
that it interfered with everything else.

I already told you ,Darling Dufus, I don't do mops or work inside
septic tanks. In particular, I don't want your job where they go
together.

Our pot core transformers resonated very nicely at around 56kHz, and
that was regardless of how the windings were configured.

It's a shame you're in such bad shape. I'm sure there are some
county or faith based organizations that could help you. Folks
in your condition deserve at the very least a chance and a hand
up.
