TPS62240: TPS62240 Simulation Error

Roy Swanke

Part Number: TPS62240

I get an error when trying to simulate the unencrypted Spice model in LTSpice:

"Warning: can't resolve .param v_r=v_rail"

Any ideas what could be causing this?

Hi Roy,

I can take a look and see if I can figure out why that happens.

I've checked that it works on the PSPICE simulator. You can download it here https://www.ti.com/tool/PSPICE-FOR-TI

Hi Roy,

I had a look at the model. A small change may help fix the problem.

On line 389 of the library file, change V_R = {V_RAIL} to V_R=1

Best regards,

Hi Roy,

Were you able to run the simulation? I am closing this thread. You can reopen it by commenting here.

This did not resolve my issue. The model still wouldn't run in LTspice. However, I was able to get the simulation working in Cadence Pspice.
