TINA/Spice/TPS53667: Simulation Error and Extra Pins on Model
Part Number: TPS53667
Tool/software: TINA-TI or Spice Models
So if I were to setup this TPS53667 to work with a CSD95490Q5MC, is there an example how to do that? Do I need to be exercising the CLK pin to get the model to work eventhough I'm not using that in the application?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Can you tell me which simulator are you running the model in and can you share your schematic with me?
'm running .tran 1m startup. I'm using LTSpice XVII.
Are you using the encrypted model or the unencrypted model for the TPS53667 and the CSD FET part? Both of these are encrypted in the product folders in PSPICE so you cannot directly import it into any other SPICE based simulators unless you use the unencrypted models. You will need to contact your local sales representative to request the unencrypted models.
I loaded in the new .lib file and still get an error when I run the simulation. Error is u1:_u9_U20:1:e_abmgate1: Unknow circuit node. "nc_16" requested in behavioral source
I tried to probe some more nodes in PSPICE model and could not find anything which might cause a problem and unfortunately cannot check each internal node in LTSPICE as we do not support external simulators. Given below is the setup and simulation in PSPICE, it would be helpful if you could try matching up the test case or even running in the same tool.
