LM5175: TINA doesn't like the TI LM5175 Files

DJ Nyberg

Part Number: LM5175

I asked a related question re my attempt to use the LM5175 in kicad. Pending that, I'm trying TINA TI.

Add spice macro dialog sequence fails when I try to create the part using TI's own pspice files. It would be nice if the file TI made for this part worked with the tool TI licenses for people to use. Can this be fixed, please? thanks!

Hi DJ,

Thank you for your patience!

Hi DJ,

The easier way to create TINA mode is not to use the Pspice model by yourself. You can create a Webench circuit with the LM5175, and extract is to TINA, then update that circuit in TINA. You should only change the external components but not touching the LM5175 IC model generated by Webench.

Thanks,

Yes, understood. I imagine a lot of people are out this week; looking forward to hearing when it's feasible.

Hi DJ,

Are you able to generate the TINA model from the Webench?

Thanks,

Youhao

Today I can't; it hangs. Only a few days ago I did manage to generate some results from webench, but I don't think 5175 was one of the options it offered. I did succeed in simulating, in TINA, a 5118 design it generated.
