LM5180-Q1: PSPICE model issue

Part Number: LM5180-Q1
Other Parts Discussed in Thread: LM5181, LM5180

Dear team,

I am experiencing the same issue with both LM5180 and LM5181:

ERROR(ORPSIM-15141): Less than 2 connections at node N15746.

This node is the TC node. Can you share a solution for this?

Best regards,

  • Hello Antoine,

    Thanks for bringing this to our attention. 

    Did you download these models from their respective product folders or did you take them from PSPICE for TI directly?

    I'm able to simulate both of these models when I download them from their product folders so give this a try and let me know if you still experience this issue.

  • Hello Harrison,

    Yes, the models from the TI folder are working fine: I see that the TC feature is not modeled, and it is left NC in the provided circuits, so I think the issue lies there, because I tried adding a resistor between TC and RSET, and I obtained the same error message.

    Thanks for your support,

    Regards, Antoine
