Part Number: TPS54218

Hi,

While running transient simulation on TPS54218, keep facing error " Operating Point Not Found".

Need your help to check on our simulation file for whats going on?

Was playing with Analysis parameter but not able to solve still.

Thanks!

Hi Hoong Wei,

Is the model is not working before you change the parameters or after changing the parameters?

Hi Tanvee,

Yes by default it works.

But after we modified it to our design then it stop working.

Thanks!

Hi Hoong Wei,

Could you share the file where you are trying to capture the data? The attached file doesn't have any measurement point and I don't understand the purpose of R2 resistor (10 Ohm) in parallel to feedback divider that will drop the output voltage.
