Hi all,

Do you have related document of select the snubber value and size? Thanks.

    Hi Roy,

    Unfortunately, I do not.  The recommended value in the datasheet is used across several of our higher input voltage products.  If you want to test the RC filter's effectiveness, you can measure the voltage overshoot at plug in.  As long as there is little to no ringing at plug in, the filter is sized properly.   

    Regards,
