TINA/Spice/UCC28019A: PSPICE Model is incomplete

Tool/software: TINA-TI or Spice Models

Hello,

I down loaded the PSPICE model and built circuit around it based on the app note for this IC. On the model there is no pin 4 (VINS) and pin 7 (VCC). Here is the symbol from the model. I tried w/o the two connections hoping that they are internally specified. The model does not work showing convergence problem instantaneously. Can someone look into it. Thanks.
