WEBENCH® Tools/TPS55340: The simulation file exported from webench not working in Tina!

Part Number: TPS55340
Other Parts Discussed in Thread: LM3488

Tool/software: WEBENCH® Design Tools

Hello Team,

I am in the process of selecting the buck converter for my application. I could find the above mentioned part with my requirements and also i could simulate the same in WebBench tool.

Then i wanted to play around a bit so i exported the model to Tina as .tsc file. Unfortunately the model does not show the behaviour as it is showing in WebBench.

Could you please check the same. I have attached the .tsc file here. Please check.

Specs:

Vin : 8V - 17V

Vout : 18V @ 1Awebench_design_1799836_35.tsc

Hi Durgaprasad,

For the spec(Vin : 8 - 17 ; Vout : 18 ; Iout : 1) , We ran TPS55340-Q1 on webench and also exported to tina and compared the results where the behaviour of Tina results are almost same as Webench.

Please find the Webench and Tina results below:

Webench results:

Tina results:

Also i tried running your attached tina .tsc file which is running fine for me which is similar to above shown results.

Could you please confirm if your tina results are different from the above shown Tina results?

Thanks,

Kiran Kumar

Hello Kiran,

Please detail me a little on the simulation profile?
Thanks

Hi Durgaprasad,

Could you please let us know what exactly do you require from the simulation profile?

Thanks,
Kiran Kumar

Hi Kiran,

Spot on. No i got it up and running. I was using the 'Steady state solver' until now. It was giving some results which were irrelevant for me. May be you can explain bit about it.
Now i ran it with Transient response with 10 ms. I got the expected results.

Thanks,
Durgaprasad

In addition,
Do you have any Tina Models for the IC LM3488 as shown below:

Thanks in advance.

Hi Durgaprasad,

Currently we do not support tina model for LM3488 but you could find standalone Pspice model in the below link:
