Original question:

importing TI pspice models for UCC28711 into LT spice

TINA/Spice/TPS62130: Import TPS62130 SPICE model in LTSPICE

Part Number: TPS62130
Other Parts Discussed in Thread: TINA-TI

Tool/software: TINA-TI or Spice Models

Hi,

I dont understand how could I import TPS 62130 spice model which downloaded from link: http://www.ti.com/product/TPS62130/toolssoftware

I have look through some tutorials for this related topic but the example just shown a simple op amp import instead of complex module. I dont have clear idea on that especially I dont understand what does each file in the folder stand for. Wish there is a video or steps shown properly how does the process going through. Thanks.

    Hi Ee Wen,

    Unfortunately, we cannot support our SPICE models in LTSpice due to EULA.
    We recommend you to use PSpice or TINA-TI for observing the simulations as both models are available on website.

    Further, are you facing issues in understanding the files of TINA-TI model or the PSpice model?

    Thanks,

    Hi,

    Actually I am new to TINA, I try to export the simulation circuit from WEBENCH. I can perform transient analysis with expected result but when I trying to do dc analysis such as measuring the output voltage using voltmeter. The output voltage return is 720.01nV. My expectation is it should obtain 4.2V for this design. I also try to change the voltage source to 12V battery but return with same results. May I know where I have make the mistake? Thanks.

    Hi Ee Wen Quek,

    You will not able to perform DC analysis on Startup transient model.
    For any startup transient model tool calculates initial DC operating point at t=0 and (those value will be close to zero for all nodes) and then it calculates DC operating point for discrete time (depending on step size). So, a transient model is not suitable for DC analysis.

    If you want to observe steady state values quickly then you can try to export steady state test bench from Webench.
