UCC21750: Pspice model fail to run

Part Number: UCC21750

Hi guys,

I download the  UCC21750 PSpice Transient Model from (UCC21750 data sheet, product information and support |, and run it with Pspice for TI ver. 17.4-2022. The model fail to simulate and the error information is shown in the picture attached. I wonder how to fix this problem. 

I appreciate your help.

  • Hi Minghang, 

    This is not an error message. If you're using imported models in PSpice for TI, as said in this pop up window, you'll be able to put down only between 1 to 3 markers to measure current, voltage, etc. We recommend you putting down these markers before running the simulation, then click "ok" when this pop up window appears. In that way you can view the simulation results. 



  • Hi Vivian,

    I have put down these markers and the simulation works. 

    Thanks and have a nice day!

    Best regards,
