LM5143: Soft start time, when both SS1 and SS2 are tied together

Part Number: LM5143

Tool/software:

Hello team,

On the datasheet section 10.2.2, both of the SS pins are tied together and connected to 68nF cap.

And it says Soft Start time is 2ms with 68nF cap, but I think it should be 1ms because both of the SS pins are going to be charging the 68nF cap.

Could you check if my understanding is correct?
I have tried on PSPICE, but it resulted 2X faster soft start time.

Best Regards,
Kei Kuwahara
