    Hello Houwei,

    This RC network is meant for filtering noise generated at INN and INP switch nodes from getting onto VIN supply. It is not meant for creating a delay. Although higher RC values work, I would not suggest using them as all validation of the device under various conditions was done with 100 ohm, 0.1uF. There is no validation data available with higher values.

    Kind Regards,
