LM2578A: Tina-ti simulation for troubleshooting manufactured cards

Louis LAS
Prodigy 10 points
Part Number: LM2578A
Other Parts Discussed in Thread: TINA-TI, LM3578A

Tool/software:

Hello,

I am currently trying to simulate, on Tina-TI, a circuit. This simulation will be helpful for troubleshooting manufactured cards with an electrical fault. I need to replicate the correct functioning of the product in the simulation. Therefore, using the same components as the original BOM is essential to this simulation. My simulation must be identical, or almost identical, to the manufactured cards.

This circuit uses the component LM2578AN, however, I am unable to find on your website any SPICE simulation model for this component. I have not found a similar model that I can use in my simulation without changing the other elements of my function (making it useless to create the function because I need the simulation to be as similar to the manufactured cards as possible). I joined the function I am struggling with.

I would like to know if it would be possible for you to either help me find a component very similar to the LM2578AN that would be compatible with my simulation without any major changes (I need to use the same type of components around the LM2578AN with the fewest changes possible). 

If this is not possible, please, suggest another solution.

Best regards,
Louis LAS

    Hi Louis,

    As this is an older part, it does not look like we have a SPICE or Tina-TI model available for this. I will note too that as TI has transitioned to PSPICE for TI, TI does not officially support Tina-TI for simulations and our recommendation is to use PSPICE for TI. All this being said, the support that we can offer for your request may be limited.

    I did see that another part, the LM3578A is linked with this part. This part also seems to have an excel calculator that is capable of some simulations here: https://www.ti.com/tool/FLYBUCK-FLYBACK-DESIGN-CALC

    You might be able to use this calculator tool to simulate certain aspects of your design, although I am aware that its use may be limited for what you might need.

    Thank you,
