LM5121-Q1: Noise simulation in PSPICE for TI for LM5121-Q1

Ritu Jain

Part Number: LM5121-Q1
Other Parts Discussed in Thread: LM5121

Tool/software:

I am not able to run noise simulation on LM5121-Q1 circuit in PSPICE for Ti. I have Ac/noise enabled set up , but in plot widow, noise icon never gets active.

Any help will be greatly appreciated.

thanks,

Hello Ritu,

Thanks for using the e2e forum.

For LM5121 we only have a PSpice transient model available. There is currently no average model, which would be required for small signal analysis.
The transient model is a strongly simplified version of the physical IC, so simulations over temperature, component variance or Monte Carlo are not possible.

I am very sorry for this inconvenience.

Best regards,
Niklas
