The LTC3729 datasheet states that the if the output voltage falls below 70% then the RUN/SS pin will start discharge the softstart cap. I do not see this occur in the model when I apply a heavy step load to the output. The Run/SS pin never discharges even though I'm in a current limit and voltage has folded back well below 70%. I'm trying to better understand how this behaves to balance softstart time vs not latching off, but the model does not appear to work properly.
