    Hi all and a very Happy New Year ;)

    This is my first post & look forward to learning & helping when I can.

    I need a TOP243Y or TOP244Y switch regulator IC for a Switch Mode Power
    Supply.

    It's similar in appearance to a stand TO220 transitor, but it has 6
    legs.

    The only place I can seem to get one is digikey USA, but shipping to
    the UK is a flat £35 ;-(

    If any one can help, I'd be really grateful.

    Many thanks - Richard (UK) - Skype ' timetec '

    I get 'em from Mouser. BTW, its not a regulator, its the
    oscillator/driver for the transformer.

    If you can persuade Power Integrations you're a serious designer they'll send
    you free samples.

    Farnell stocks them too.
