LM96063: Side effect of adding capacitor at PWM pin

Part Number: LM96063

Dear team,

We face to system noise issue on customer's board. They solve this issue by adding 100pF at LM96063 PWM pin.

Are there any issue of adding capacitor?

We have check PWM slew rate and no big impact of PWM.

Hi Ben,

Adding capacitance on the PWM can affect the slew rate could cause issues if the edges become to slow. If you do not see a big impact with that then I do not see any other concerns.

Thanks,

David
