TPS629210-Q1: PSpice Model Issue

Mayur M Bharadwaj

Part Number: TPS629210-Q1

Hello,

I downloaded the P-Spice Modem for TPS629210-Q1 from TI website, and tried simulating, however, it is not giving any output. The same circuit which worked in Webench, it is not working in PSpice.

I also tried it in PSpice for TI, where the libraries are inbuilt, but the same issue was observed there also.

Can you please help me in resolving this issue if its a connection issue, or can you guide me on what could be the issue?

Thank you.

This is related to the initial operating point calculations and is likely related to the input source. You can try going to the Pspice menu -> Edit simulation profile -> Analysis -> And check the Skip initial transient bias point calculation (SKIPBP) box and then try.

Attached is a project that works.

Thanks, Amod,

Hi Mayur,

Please try Amod's suggestion to fix the issue. Another way, you can use pulse as input source, this can also fix your issue. Please see my slide as attached.
