Part Number: LMG5200
Tool/software: TINA-TI or Spice Models
One of my customers is experiencing issues with the LMG5200 PSpice model. Their message below:
I Have the lmg5200.lib file from TI Web site. (LMG5200 PSpice Transient Model (Rev. B))
I wanted to revive the LMG5200 simulation, I took licensed Pspice and try to run the models
Got errors I can’t resolve:
Attached “run”.out log file
Note the error immediately after .END of the netlist
“ERROR -- Convergence problem in transient bias point calculation”
I tried “auto – convergence” feature, it run longer time but still gives the same error
What could be causing this error?

In reply to Nikhil Gupta (1):
Nikhil, The customer is simulating the LMG5200 in a very large circuit with many other devices. They said the simulation runs well using discrete GaN transistors from another vendor instead of the LMG5200. Their simulator is SLPS (www.pspice.com/.../pspice-slps. I will reach out for more details. Any guidance will help me so I can ask for the right information. - Daniel
Thank you for helping us fix the LMG5200 simulation , We have updated the OrCad release files and this should be reflected in the new downloadable model in 1-2 business days.
