LMZ35003: LMZ35003: Soft-start time

Hi team.

When VOUT=12V, is it possible to set Slow Start to a short time such as 7ms?

The data sheet says 17ms (SS/TR=22nF) is recommended, but why?

    Hi Takahashi-san,

    Thank you for posting.  I think there is a misunderstanding. The datasheet does not suggest you to take 17ms.  Instead, the able show the relationship of Css to the soft start time.  In other words, it gives a few points on how to program the soft start.  You can choose 7ms.

    Hope this clarifies.

    Best Regards,

    Youhao
