Part Number: TPS82130

Hi team,

My customer has below questions about TPS82130 soft-start time. Please kindly help to answer.

What is the maximum SS time of TPS82130?
Is 25ms too large? Any potential risks to use such large SS time?

Hi Miranda,

I am not aware of a maximum SS time spec for this device. I would not be concerned with 25ms (~50nF Css capacitor).

Does the customer want to use a long SS time due to large output cap to limit inrush current, or to achieve a certain power-up sequencing, or for other reasons?

Regards,
Kris

Hi Kris,

Thanks for your comments.

The 25ms time is required by power-up sequencing in my customer's application.
