TPS543C20A: TI supplied PSPICE model for power supply not converging.

Other Parts Discussed in Thread: TPS543C20

Hello,

I am an LTSpice user trying to learn PSPICE. It's a big challenge so far. Has anyone downloaded the TPS543C20A PSPICE model from the TPS543C20 product support page? I am having a hard time getting the simulation to converge. Any help would be appreciated. I would provide more data on why the simulation fails, but I can't fine the error log anywhere.

Hi Chuck

My colleague will check it and give you a feedback early tomorrow, thanks!

Hi Chuck,

On my end, the TPS543C20 PSPICE model from ti.com is working fine with the default configuration.

What conditions are you attempting to simulate? PSPICE simulations do face convergence errors occasionally during corner cases. One thing to try as a solution is turning on Auto-Convergence. This can be found from: Edit Simulation Settings > Options > Auto Converge > Check box for AutoConverge. If you are still having trouble, please feel free to zip up your project files and share them here

Best regards,

Britton

Thanks Britton for the quick response. Circuit is simulating now.
