Pspice for TI Simulation with TPS62903 part

Other Parts Discussed in Thread: TPS62903

Hi,

I am looking to do a simulation in Pspice for TI with the TPS62903 part. I have a simple simulation made up, but it is not giving me the expected results. Can someone check it to see what is wrong with it?

Thanks

Can you please share the issue you are facing? I'd also recommend sharing the project file.

Thanks,

I have simplified the schematic to the picture below:

I expect to get an output of 1.2V but when I do a time domain simulation, I get 5.33mV output voltage.

It looks related to the initial conditions so I would try going to Pspice -> Edit simulation profile -> Analysis -> And check the Skip initial transient bias point calculation (SKIPBP) box and then try.

Attached is a project that works.
