LM2594: Attempting to simulate LM2594

John Treubig

Part Number: LM2594
Other Parts Discussed in Thread: LM2674, LM2574,

Looking to simulate an LM2594 design, but WEBENCH is not offering it as an option. Is there something I'm missing? It does offer LM2574, however I've got an existing design that uses an LM2674 that I'm attempting to drop in a different component and the LM2594 pinout is similar to the LM2674.

Hi John,

Thank you for reaching out. The Pspice models are available at ti.com. You can access these at the following link, and scroll down the page to find them.

Thanks Youhao. Because you focused me on the Ti website part detail, I found that the Webench simulations are still available. Was able to simulate the details. I also found that I can bring up Webench for the LM2674M-12, but it will not simulate. Is there something we can do to permit this?

Hi John,

I see the LM2674 Webench model, but somehow the simulation is disabled. I need to direct this question to our Webench group.

Thanks,

Youhao

Hi John Treubig

Electrical Simulation is not yet enabled for this device. We will enable the same and it will take tentatively around 3 weeks.
We'll keep you posted regarding the status.
Appreciate your support.
Thank you

Best Regards.
