LM5180-Q1: Need guidance on how to evaluate loop stability

Part Number: LM5180-Q1
Other Parts Discussed in Thread: LM5180, TINA-TI,

Hello,

I am trying to evaluate the stability of a flyback converter that uses the LM5180 IC.  I have access to LTSpice, and TINA-TI, but do not have access to PSpice.  The only TINA-TI models I can find for this part are transient models that will not work with a AC response simulation, and I cannot import the encrypted PSpice model into LTSpice.  Looking at the WEBENCH tools for this part it does not seem to provide any stability plots for the suggested design.  How do you recommend evaluating the stability of this design?

Thank you,

Nick
