TPS562242: TPS562242DRLR Simulation Error

Shangugapriya G

Part Number: TPS562242

I am trying to simulate TPS56224 Voltage regulator at PSPICE.

But I am getting the error “ undefined parameter steady state” after that I searched in TI website and added the parameter SS=0, still there is a error.

Here I have attached the images for your reference.

Did you change anything in the simulation model? Could you run successfully after download it from ti.com website?

Thanks!

I didn’t change anything in simulation model.

Yes. after downloading from website I just imported the symbol, when I am trying to run the simulation its giving the error message which I mentioned.

Hi Shangugapriya

Why you need to imported the symbol? You can just directly run the simulation without import the symbol?

Sorry for the language. I have not imported the symbol. I added the symbol in the simulation Pspice. We have not done any modifications in the simulation files.

Hi Shangugapriya,

If your error the same as above, you can just delete the diode in the schematic. It's not a must requirement. Then you can run the simulation to try again.

Thanks!

Hi Shangugapriya,

If you just open the model which is downloaded from ti.com, you can just remove the diode connected with EN and click the Pspice-Run button without error. Could you please try to follow this two steps? If you still can't solve the problem, please send me your simulation file so that I can debug for you. Thanks!
