Dear Sir/Madam,

I want to use TPS82130 as an inverting power module introduced in www.ti.com/.../tiducv2a.pdf.

And I try to simulate using TPS82130 PSpice Transient Model (Rev. B).

But results not as expected, and model is encrypted.

Is the simulation possible an inverting power module circuit with supplied model?

Best Regards,

Kazuo

Kazuo,

The spice model has the GND pin hard coded to GND. For the inverting buck boost, the GND pin must be set to minus Vout. That is why the price model will not work for the inverting buck boost application.

Dear John,

Thank you for quick reply. I understand.

Do you have a plan to provide the model its applicable for he inverting buck boost application ?

Best Regards,

Kazuo

Kazuo,

There is not currently a plan for it. If there is an urgent case for it, I can suggest that it be added.

Dear John,

It's not so urgent, but if we get the model, it's very happy for us.
Because, now we have been designing a instrument including designed by an external company.
The company adopts TPS82130 for its power supply part as generating negative power supply.
We have to verify the circuits designed by the company.
If possible, thank you.

Best Regards,

Kazuo

Kazuo,

Let me see what I can find out. It will be after the holiday.
