Hello,
I am working to simulate the TPS543820 model on PSpice for TI. Our customer needs Vin = 4.5~6V, Vout = 1.20V, and Iout = 4.2V. When I try to run the transient simulation, it is taking a very long time to run (after 2 hours, the simulation progress is stuck at 2%). Are there any suggestions to speed up this time, even if we compromise accuracy.
Thank you.
Hello Kyle,
Could you please share the project files with us so that we can have a look?
We have downloaded the model from web and modified the schematic for Vin=5V, Vout=1.2V and Iout = 4.2A.
The model simulated fine and took around 2 hours to complete (Please see attached).

Hi Kyle,
Please always try and use simulation parameters same as that of the model on product folder.
For reference, we have added below snapshots of the parameters that needed to be changed in the project shared by you.
This helped solve the slow simulation time.
Although we did not run the model completely as it takes 2+ hrs to simulate, it reached 24% in half an hour which is accurate.
