Hi,
I am using LT Spice simulation tool to simulate one design which includes LM5017, unfortunately I am getting time out error saying that "Time step too small, trouble with node u1:u2_qb_nd" where u1 is LM5017 ref designator. See spice error log below:
Please help me to understand the issue here.
