    Hi,
    

    Is there a formula or graph that shows the relationship between the capacitance of the capacitor connected to the RUN/SS pin and the soft-start time?
    

    I do not know how to determine the capacitance for the soft start.
    

    Regards,
    

    Kazu

    Hi Kazu,
    

    

    I hope this thread can help you:
    

    (+) LTM8051 Soft Start capacitor vs soft-start time - Q&A - Power Management - EngineerZone (analog.com)
    

    This is the necessary information that you might need.
