    Hi everybody,

    I have a little problem to understand how this circuit works.
    I think that it produce an inverting input to PWM chip.

    I made a schematic wit values of components.

    Can someone explain me how does it works, I will really appreciate for any help.

    Thanks and have a nice weekend.
