LT8306 simulation issue with secondary-side synchronous rectifier

Category: Software
Product Number: LT8306
Software Version: LTSPICE(x64) 24.0.12

Hi,

I'm simulating LT8306 and LT8309 in LTspice but can't get them successfully start up. The circuit is from Figure 30 in datasheet.

I guess it's the same reason with this thread LT8306 - Stops Switching but don't know how to fix it. I wonder if it's caused by the soft-start short circuit protection and could you help get the model running. Thank you. 

Kind regards,

Cain
