tps51116 tina-ti model error

Can you post one of your models?  We can try to duplicate the problem.

how do I do that?

You could post it as an attachment...use the paperclip icon.

0804.{Tina9-TI-02182013-150130}.zip

This paperclip thingy is mighty faint to figure out!

let me know if this works.

thnx

Ok,  I got it.  We'll let you know what we find.

Hi Robin,

We do not need your entire TINA-TI directory, we only need the TSC file that you are trying to simulate. Can you please attach just the TSC file?

Thanks,

I sent it to you off line...

6558.ddr2_tina.TSC

here it is : the raw tsc file alone

thnx

Robin,

One of our engineers here too a look at and has proposed the following solution:

The engineer used the EVM application and changed it to use the values of compensation and load capacitances with the MOSFETs used in your design. They were able to get switching, please use this and make any further changes as needed.

8446.TPS51116_STARTUP.TSC

Please let us know if you have any additional questions.

Britt

thnx for the model.

Seems I cannot export the model to my installation to become a part of the library of models.

How to do that anyways?

+ an issue

I gotn a failry fast desktop.

It took too long to get to 30 %...outputs were still in 100s of mV

so I stopped it.

Looking into the parameters, I noticed that all VDC values are 0 & if I put right values, wont run. Gives an error.

does the "embedded" model pick up input voltage values & 5V bias?

doubt.

Is this model good enough to run phase margin analysis with different LC &R on the output?

What are you trying to export to?

This is a transient model.  It is processor intensive.  Even with a fast PC it takes along time to run even a few msec.

The node voltages are calculated based on time.

You cannot do loop analysis with teh transient model.  That requires an average model.
