    Default DC/DC Converter 24Vdc to 5Vdc

    Hi everebody here!
    I've designed a DC/DC converter for a MUX card which needs 5Vdc/1A power supply. But I'm not sure that it will work properly. Can you advise me about chossing of capacitors? And are that connected correctly? Thanks in advance.

    hi,
    The datasheet for then 25-2411 says a 100K pot for set, not 10K.

    Why have you added C2 and C3 capacitors, there is no mention on the datasheet.

    Otherwise it looks OK.

    EDIT: do you plan to use the 24V input side voltage as part of the +5V logic control.???
