TPSM82901: PSPICE for TI Model Does not Work

Mark Freeman

Part Number: TPSM82901

Tool/software:

The Webench design would not simulate properly: the output voltage never exceeds mV level. I translated the design to PSPICE for TI: that also failed to simulate properly.

Hi Mark,

I am properly able to simulate the IC in pspice and even webench.

Can you recheck your settings and download the pspice model from TI website again.

Share the simulation results what exactly you are getting in the output.

Startup simulation works, but Load Transient does not.

I checked it and its working as shown below.

But why is there 11V as Vout because Webench/IC has only 5.5V as max Vout,

can you please recheck

I have working hardware, so I won't bother with tracking down simulation issues.

OK Mark,

Hope the hardware is working fine.

Thanks,
