TINA/Spice/LM2576: what is difference between (just) Pspice model and Pspice transient model.

Tool/software: TINA-TI or Spice Models

I always don't mind suffix 'TRANSIENT model' in Pspice.

Currently I have needed to use 'LM2576-12v' model, so i tried to find the model library.

But I couldn't find the thing that is same with LM2576-12v model.

I could only get a model named 'LM2576HV_TRANS'.

I know the meaning of HV. but, what is difference between (just) Pspice model and Pspice transient model.

<These pictures are 'LM2576HV_TRANS' model and the sumulation that i found>

<This picture is the model 'LM2576-12v' that i want to find>
