TPS22811: will SLVMDX4.ZIP model will work for DC sweep Analysis?

Sagar kumar

Part Number: TPS22811

Tool/software:

Hi,

I downloaded SLVMDX4.ZIP model and import in LTSpice tool for our simulation. We are able to get transient analysis by using this tool in LTSPICE. Please let me know can we perform DC sweep analysis as well on the same module in LTSPICE since we are not able to get proper results when we performed DC sweep analysis?

Thanks

Hi Sagar,

If transient analysis is working with LTspice, then full model should also work. I will have to check this on my end also. I will get back to you by end of week.

Best Regard,

Hi Sagar,

Can you share the error message. I asked one of my colleague who do lot of spice modeling. He feels that this is not a Pspcie-LTspice related issue and more likely a convergence issue.

HI Arush

Here Green is input which i am sweeping from 11V to 14V while blue line is O/P.

While in AC analysis i am able to see current at O/P and Voltage at O/P.

Thanks

Sagar

Hi Sagar,

Let me try this on my end with pspice.

Hi Sagar,

I was able to run this simulation on my system and it is fine in pspice. I do not have LTspice. Is it possible for you to try pspice for Ti.

Best Regards,
Arush
