LM5022 Tina Spice models vs reference design.

Other Parts Discussed in Thread: LM5022, TINA-TI

If I look at the LM5022 tools & software page there are Tina reference designs, they load into Tina and show a complete schematic.

I can strip the schematic and build my own schematic around that works.

Maybe a stupid question but how do you load a Tina TI Spice model in Tina?  In that case I assume I just have the device and can create my own schematic around.

The .zip file contains a .lib, a .tsm and a .tld file.

Can you describe the procedure to load the model in Tina.

Can you also use the Pspice models in Tina, or alternatively does Tina allows loading non TI Pspice models?

Last question: There are average and a transient model of a number of devices.  Which one would you use for which simulation?

    Jan,

    Good questions. The .zip file contains a .TSM file which is what we call a macro file. This is a self contained file that holds the symbol information, connectivity, and the spice model for simulation. To use this file, simply start up TINA-TI and select the Insert-->Macro... feature from the top bar.

    This will open a navigation window so that you can navigate to the .TSM file on your computer. It will then be placed into the schematic window.

    The additional files were originally used to import devices into the menu system of TINA-TI. The older methodology is not used currently and we prefer to use the .TSM file since it has all of the information needed.

    Transient and Average models are normally present for Power devices. A transient model is used for any time based simulation (startup, steady state, load/line transients, etc.). An average model is used for an AC simulation with a power product that will produce a Bode Plot. The average models contain only a subset of the device (anything that would affect the stability of the feedback loop of the device). The only exception to this is the LDO models that are produced. They will not simulate a Bode Plot, however, PSRR can be simulated with the transient model (a first order approximation).

    I hope this information helps.
