    Hello ,

    I want to increase tON time in that PWM circuit,How can I success it and how can I create a %50 duty cycle?

    Thanks for help..[​IMG]

    A fixed voltage of 0.5V on the MOD pin should give you a duty-cycle of 50%.
    Refer to LT6992 datasheet for more info.

    Most of the models that come with LTSpice also have a test fixture supplied with them.
    Simply drop an IC model into the schematic, and right-click on it. You'll see the option to load the models' test fixture, go to Linear Technology's website for the datasheet, or cancel.

    I suggest that if you want to run the test fixture or make any changes to it, you save it in a different directory under a different name first.
