UCC28730: How to add spice model to TINA simulation

Other Parts Discussed in Thread: UCC28730, TINA-TI

Tool/software:

There is no generate part option under the "tools". So I tried to use "New Macro Wizard" to import UCC28730 spice model. I pick the netlist file to generate it but it gives me "Invalid device" error.

Can you please help me on how to import the spice model of UCC28730?

Thanks.

    After i get the invalid device error in TINA-TI, it says there is something wrong with this line in the file: $CDNENCSTART 

    so, the problem is i guess TINA-TI can't read this file because its encrypted, is there a UCC28730 simulation file suitable for TINA-TI?

    Hello,

     

    Sorry you are having issues importing the UCC28730 PSpice model into Tina.

     

    I researched this and is looks like the PSpice model’s netlist is not compatible with Tina.

    I found the following information on the web that may help you resolve your importing issues.

     

    Here's a detailed breakdown of the process:

    1. Download the PSpice model:

    Obtain the unencrypted PSpice model file (usually with a .LIB or .CIR extension) from the manufacturer's website or a trusted source.

    1. Prepare the PSpice model:

    Check for Compatibility: Ensure the PSpice netlist file is compatible with TINA. Some PSpice netlists may contain statements or formatting that TINA doesn't support. You can use TINA's "Import" feature to check for compatibility.

    Edit if necessary: If the netlist has syntax errors or formatting issues, you might need to edit it in a text editor to make it compatible with TINA.

    1. Import the PSpice model into TINA:

    Open the New Macro Wizard: In TINA-TI, go to Tools > New Macro Wizard.

    Name the TINA model: Give your TINA macro model a name.

    Select the PSpice file: Browse to the location of the downloaded PSpice netlist file (.CIR, .LIB, .MOD, or .TXT).

    Choose a symbol (optional): You can optionally choose a symbol for the macro model. TINA can auto-generate a shape or you can select one from the library.

    Save the TINA model: Save the .TSM file.

    1. Use the TINA macro model:

    Insert the macro: You can insert the newly created .TSM file into your TINA-TI schematic.

    Place the component: Use the macro model as you would any other component in your TINA-TI design.

     

    I do have another option.  You can actually use TI PSpice to model your power supply.  You can download this simulator for free from ti.com.  The following link will get you to a debugged PSpice model that is simulated in a full power supply.  It will save you time in the debug process.
