Good day. I hope you are well.
Our customer is using the PSPICE model for the and they have the following question.
"I'm using the LM5180-Q1NGU_TRANS spice model in pspice ti 2020
It is hooked up correctly, but the internal model of the 5180 appears to be broken
the problem is related to the "TC" pin
it appears to be not connected inside the model
