DC to DC Step Up ???

Hi all,
can someone describe what a dc to dc step up circuit is.· From what I can tell from this link, this circuit takes in a 1.1v upto 4.5V input and generates a 5V output.· Does this mean I can use real small volt batteries in that range and still get 5v out of this puppy?

thanks in advance

    Yep, thats what step-conversion is all about.

    BUT, that does not mean you can draw several amps from the high side with only a watch battery on the input side!

    As a rule of thumb: input volts x input amps = output volts x output amps x .80, your mileage may vary.

    Cheers

    Try searching the Wikipedia for voltage conversion or "boost converter".

    Check out this thread 300 Volts in a roll of film
