    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.

    have you checked digikey?

    jameco?

    anything?

    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.

    Or try something like in a an LTspice simulation (you will have to modify as needed).

    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. ;)

    Oh, well, let he who is free of mistakes and smoked components throw the first rock :D
