Hi,

I tried to import a LM3478 PSpice model but during the process to create the macro, it aborts and the follow message appears:

Please, can you tell me where is my mistake? Thanks

Matteo,

Your error message did not come through. Can you post it again? Also, are you using the latest version of TINA-TI? It has several enhancements catering to model imports.

Matteo,

Please change the .SUBCKT statement from:

.SUBCKT LM3478_TRANS AGND COMP DR FA_SD FB ISEN PGND VIN

to:

.SUBCKT LM3478_TRANS AGND COMP DR FA_SD FB ISEN PGND VIN PARAMS: SS=0

The steady state parameter is added in the PSpice reference design and was missing from the unencrypted PSpice model.

I believe that this will correct the error.

Hi Matteo,

LM3478 PSpice model has been updated by including the SS parameter in the .SUBCKT. Now you can use it for your simulations.

Thanks,
Krithika
