TINA/Spice/UCC25600: VO615A

Part Number: UCC25600

Tool/software: TINA-TI or Spice Models

I am getting a convergence error when I try to run a transient analysis of my circuit. I notice that this happens when I use the V0615A optocoupler in my design? What is the cause of this and how do I fix it?

I got the design for the optocoupler here

My design can also be found here for reference.
