    Hi everybody,

    this is my second post with the same title.

    I am trying to understand how does this circuit works.
    I have changed first schematic and I think that now is correct.

    Can someone explain me how does it works with one NPN, PNP transistor and one MOSFET.
    I think that this circuit is producing an inverted input for PWM chip. Am I wright? How does it works?

    Thanks in advance
