I am trying to simulate Buck converter LM536005-Q1 in ltspice. I have imported third party module of LM53600-Q1 from TI website. I have created symbol and stated running simulation but I did not get the waveform window. When I check the log, I am getting following error enter image description here
The simulated circuit is attached here enter image description here
The link for the third party model downloaded is given here https://www.ti.com/product/LM53600-Q1?keyMatch=LM536005&tisearch=Search-EN-everything#design-development##design-tools-simulation
I am not getting how resolve this issue. Somebody please help.
I don't know what is the purpose of the IC, but I think your problem is with the schematic capture.
If you try the simulation via spice code (create an empty file and open it with LTSpice) you can at least simulate. I tested the code below it I've got the result in the figure.
I don't know if the results make any sense. That's up to you. But with the code you can at least to simulate and test some parameters. I simulated only 1.2 ms because it was costing me the whole processing power and took about 10 min for that.
Important to notice that:
** Test Simulation
** options and includes
.include LM536005-Q1_TRANS.lib
*** Circuit
** Your IC Terminals from .lib file
** AGND BOOT ENABLE FB GND PAD RESET_N SW SYNC_MODE VCC VIN
** The connections
* x is the spice letter for subcircuits
* see the .subckt entry in .lib for details
