TPS82130: SS pin capacitor setting problem

Part Number: TPS82130

Tool/software:

Hi team,

The customer has an emergency problem about the Css setting. They want to use 80nF capacitor to achieve 40ms soft start when the Vref used in circuit is 1.25V. By calculation as the datasheet suggested, 80nF is acceptable in device level.

Question:

1: Is 80nF capacitor used acceptable in device level?

2: What will be the potential effect to the device if the soft start time is setting too long?

Best regards,

Damon Luo
