UCC20225A-Q1: Class-D simulation convergence problem with UCC20225

Part Number: UCC20225A-Q1
Other Parts Discussed in Thread: TINA-TI

I am simulating a Class-D amplifier circuit. When i simulate it part by part , i get the proper simulation results but when i integrate the complete chain, i am getting convergence issues.

I have attached the tina-ti file.

Please check and let me know if i am missing something or if something is incorrect.
