Hi Team,

We are using TPS544B25 to generate the core rail of FPGA.

Can you please review the excel sheet of all voltage rail ?

Voltage and current requirment are in excel sheet name.

Hey Rajat,

All the excel sheets look in order. If the ripple and transient response is how you want it, next I would recommend using the pspice model to further validate your schematic. The model can be found on the product page.

Thanks,
Caleb

Hey Perez,

Thanks for the review.

Are you suggesting to run the simulation on webench or on PSPICE for TI?

Thanks

I was referring to PSPICE but you could also do Webench if you please. Definitely get a PSPICE sim running though.

Thanks,
Caleb

Meanwhile I will run the simulation on webench.

Thanks

Hey Rajat,

There is plenty of documentation online in regards to using PSPICE for TI. See the links below:

More can be found by searching "PSPICE for ti" in any search engine.

Thanks,
Caleb
