SG3525 LTspice simulation SS pin Problem

Thread Starter

I am using the SG3525 model given in this thread.
Almost all functionalities seems to be working. But the soft start pin is showing a voltage of around 56Volts and when I try to pull this down to discharge the SS capacitor and simulate shutdown, the pin delivers huge Amperes and PWM is not shutting down. But the other dedicated "Shut Down" pin is working as expected.
Is there anything I am missing about, that pin's functionality?
Thank you.
