    Hello,I've got a 12V battery but I want to step the voltage up to be 24V.. I don't need much current from the step up circuit(Even the circuit limits the output current at 3-4mA or more is OK)
    Please,show me the circuit
    Thank you very much :)

    Check this out. It's cheap and simple.

    I'm going to get back to it soon to improve the sensitivity to input voltage, but that may not matter for you.

    Beware that it's not current limited, but it would be fine for the small current you need.

    Thank you for the circuit Steve, in fact,I'm really happy with the higher current limit because I might apply it to the other high current works :)
