TINA/Spice/UCC28070: TINA MODEL

Tool/software: TINA-TI or Spice Models

Hi,

i was assigned by a project .It  is basically an ac/dc converter design with TI based UCC28070  controller.From TI portal i got UCC28070 based TINA schematic.But found difference between the pin configuration in TINA schematic to the one which is in the datasheet of IC. There are three pins CDR, RDM and GND not used in TINA schematic instead of them other three pins IRIPA,IRIPB and f_khz are used.not able to understand why these pins are changed.please suggest me the way to get the tina model of IC as in the datasheetslum328.tscucc28070 datasheet.pdf
