Need 6V 10A Power Supply

Hi,

Can anyone provide me the circuit of a 6V 10A SMPS along with transformer design details?

Or give me a high current regulator which will regulate a 12V 15A to 6V 10A without much components. I mean I do not have space for having heatsinks.

Regards,
Bency

6V * 10A = 60 Watts power out.
If you get a design that's 85% efficient (which isn't bad at all) then you'll have 66 Watts input. You'll have to get rid of the 6 Watts of heat somehow, or your project will have a melt-down.

If you "don't have room for heat sinks", you better re-think your entire design.

I would boost the output of the National Semiconductor Simple Switcher IC with an external tranasistor (bipolar or MOSFET) to step your 12v down to 6V.

Can you give us more details on the project? Maybe there is a better way to do it, like changing the transformer for one with a center-tap.


I'm confused. Why 6V * 10A is = to 138.6 watts? Wouldn't that be 60W?
Thank you for correcting my stupidity. All I can offer as an excuse for my original very incorrect reply is that the coffee had not taken effect yet. :rolleyes:

WOAH, I gotta get me some of that coffee. Maybe that will help my calculations... which are usually grossly missed. ;)
