TPS548A20: Soft-start Time

Part Number: TPS548A20

Tool/software:

Hi,

One of my customers has a question about the TPS548A20. The design checklist shows 120us soft-start time, however, the SPICE simulation suggests a 4ms startup time.

Is there method in we are missing for calculating the actual soft-start time in the datasheet?
