• LT3799-1 Abs max spec of FB pin


    I would like to know about the absolute maximum ratings of FB pin on LT3799-1.

    According to the datasheet, the positive max is 3V. How about negative? Is that -3V?

    Thank you in advance.





    can the LT3799 be used as a  dc converter with ac input? 

    Apparently, a TM PFC regulator in voltage mode can convert ac to dc through a flyback operation- pretty similar to LED circuit but the pure dc regulator must regulate the output voltage.

    I tried to simulate the LT3799 being driven by 50 Hz supply, not the 600 Hz as in the Linear's example (jigs).

    The input current did not follow the input voltage at 50 Hz, just the opposite as it was at 600Hz.

    Why is that ?

    Is the PFC is depended…

  • HMC666_using IF pin without 1:1 transformer

    Hello Team.

    1:1 transformer applied in IF pin is expensive.

    so we want to use without transformer.

    is it possible that?

    Can you support solutions?


    Best regards,
