Hi

To have linear LED intensity dimming what should be the maximum PWM frequency if TPS922052/53 is operated at 400KHz?

    Hi KIRAN,

    It is hard to give a quantitive value as this will depend on a lot of factors like your input/output conditions, circuit designs, and how you judge linearity, etc.

    Please do the bench test to get the results.

    Best Regards,
