LMZ31710: Unencrypted PSpice Average Model

Binayak Shrestha88

Part Number: LMZ31710
Other Parts Discussed in Thread: TINA-TI,

Hi TI Team,

In the website for LMZ31710 regulator, we only have encrypted PSpice average model. Is unencrypted average model available (say in .cir format). I want to import such model in TINA-TI.

I was not able to import the encrypted PSpice average model into TINA-TI.

Thanks,

Binayak

Hi Binayak,

I will contact our modelling team to help either get the unencrypted PSPICE model or the model converted to TINA-TI format.

Hi Anthony,

Thank you and I'll be waiting for the model.

Best Regards,

Just let me know if you have any timeline you need to meet for simulating this. I have also asked our modeling team to give me an estimate on how long it will take.

Hi Anthony,

If possible, by 24th September. If required, we can add 2-3 days more.

Thanks and Regards,

Hi Binayak,

TSM file for the LMZ31710 part is attached.

/cfs-file/__key/communityserver-discussions-components-files/196/LMZ31710_5F00_AVG.TSM

I've also attached below a previous simulation I had setup to simulate output impedance for getting the R value for the RL model.

/cfs-file/__key/communityserver-discussions-components-files/196/slvmbz3c_5F00_TPS54824_5F00_avg_5F00_outputImpedance_5F00_EVM.TSC

I'm going to mark this one as resolved but if you have any issues with getting the LMZ31710 model to work, let me know. On the RL model, lets continue discussion using your other post if you have any questions.

Hi Anthony,

Thanks for providing the files.

I'll got through them, and if I face any doubts, I will create another post referencing this post.

Best Regards,

Binayak
