    hello
    I have the preovious version schematic posted in another thread, but since now the schematic is based on a app note it should be ok.
    I'm now poiting the board design.
    Any mistakes into the input part ? Source will 12volts, DC switched power supplly.
    I really would like some sugestions:
    remove islands from the copper fill ?
    copper fill, connect it to some bus or earth gnd ?
    the spacing is 60th(inches) on the inputs increase ?

    on the output I will try to get C2,C3,C4,C5 near C0 to get that ground loop minimized.
