LMZ31520/30 Soft Start time variation

K. Sasaki14

Other Parts Discussed in Thread: LMZ31520

I think the soft start time of LMZ31520/30 is selectable from 4 types value, 0.7ms, 1.4ms, 2.8ms and 5.6ms.
So please let me know the soft start time variation. We don't require the guaranteed value, reference value is OK.

And also, could you tell me the equation, if user can set soft start time freely?

Only the 4 slow start values listed in the datasheet are selectable. The slow start time cannot be adjusted to any other values.

Arrigo-san,

Thank you for your reply, and I understood only the 4 SS values are selectable. Please let me know the soft start time accuracy.
I think 0.7ms, 1.4ms, 2.8ms and 5.6ms are typ value, so I would like to know the accuracy, +/- *%.

Best Regards,

For SS timing, the typical values are normally the only values given. I will see if we have any data on this.
