    Hello,

    How much current do you need?
    If it is low current, you could take a look at the ICL7660.
    See datasheet.

    Hello,

    1 Amp will the 7660 not manage.
    Then you will have to look for an real switching converter.
    Perhaps you can find someting in the powersupply cookbook:
