    Hi to all.
    I am looking to design a PFC (input current shaping) cct for up to
    about 300W (universal input).
    I have been pointed to an ic GPTAC1300 from Green power which looks
    like it would be perfect for the job. Anyone have any experience with
    this chip.
    Are there any other "common" ic's that are easly obtainable and "cheap"
    , that have similar or better functionality.

    Your reference is a power switch integrated with a CCM controller in a
    custom TO247 body. These are unlikely ever to be either particularly
    cheap, or second-sourced.

    I would steer clear of any mfr that places power mos switch drain and
    small-signal control feedback terminals on adjacent pins of any IC
    package. This illustrates a basic naivety of practical power

    Commodity type 8-pin CCM PFC controller IC's (add your own power


    Not an inclusive list, by a long shot.

    Hello RL,
    That would give me goose pimples.
    Plus lots of European parts but if you are in North America it's often
    better to stick with the big semi mfgs here. Infineon has some real nice
    ones though, like the TDA16888 that combines PFC and PWM in one chip:
