Tool/software: TINA-TI or Spice Models

Hi,

My customer requests to verify spread spectrum function by simulation.

Is SS function included the Pspice model of LMR14030-Q1?

If it is not, is there any verifying way by simulation?

(I'm confirming background of this request.)

Hi,

Spread spectrum feature is not modelled for the part LMR14030-Q1. Therefore we cannot verify the feature using model simulation.

Thanks & Regards,

Hi, Arpan-san,

My customer would like to compare EMI w/wo SS on the simulation.

Does the Pspice model have synchronization function?

I'm considering that it can happen a pseudo spread spectrum by synchronization and oscillator.

Or do you have another simulation model which can reproduce spread spectrum?

Best Regards,

Kuramochi

Hi Kuramochi,

LMR14030-Q1 PSPICE model does not have synchronous function.

Also, we do not have any other simulation model which can reproduce spread spectrum.

Ashis
