    Sony want all my arms and legs in return for one of these puppies,
    anyone got any suggestions as to where else I might find them?
    (hopefully at a more reasonable price!)

    I don't have a datasheet either, all I can say is that the one's we
    have are made by SanKen, they are in a MT200S package as shown here;

    Here is the circuit symbol of the device;

    A scan of the device itself;

    The Sony manual lists them as DC DC convertors, they come out of a
    complex SMPS for a broadcast monitor and that's about as much as we
    know about them... aside from the fact that when they fail, they go
    out with an expensive bang, often taking other components with them
    before the fuse pops.

    One supplier has sent a quote for a DM8124N but we're unsure if this
    is the same device. (got a feeling the response is automated via an
    email request database) Besides, Sony want $55 and these guys only
    want $16, seems fishy to me.

    can anyone help me?!?!?!


    PS; newsgroups blocked at my work, forced to use google to post and
    reply, please be patient!

    It's a completely different device.

    manufactured by National Semiconductor

    Just as I expected, thanks for the confirmation!
  4. Hi,

    Knowing SONY, $55 for a part is not that bad. I had to fork out $110 for a
    monitor video amplifier IC and I had two monitors with same fault...

    Another thing with SONY, it is too often non-SONY parts do not work. Part
    look same and has same markings but do not survive for too long. I really
    suggest you bite the bullet and get it from SONY.

    Prime want AU$98 (trade) for it.
