    Hello,

    I am looking for some good application notes regarding
    How to use isolated DC to DC converters.

    Plus I am also looking for a isolated DC to DC conveters with following
    specifications
    If they are regulated, then that would be great!

    1. Input Voltage range : 5 to 6Volts
    Output voltage : 5volts
    output current: 5 Amp.

    2. Input Voltage range : 18Volts
    Output voltage : 18 volts
    output current: 3 Amp.

    3. Input Voltage range : -18 Volts
    Output voltage : -18 volts
    output current: 3 Amp.

    Thanks very much.
    Regards
    John

    Isolated from what to what ? A wall plug PSU is isolated from the mains via
    a small transformer.

    I dont know of anyway apart from just use something like a 20V DC PSU, then
    just put fixed or adjustable regulators to get the voltages you want. I
    don't see why you need them isolated ?, if you worried about short circuits
    then fuse it or crowbar it for protection. Isolation of DC sounds like a lot
    of work IMO.
