Other Parts Discussed in Thread: TINA-TI, LM5050-1,
Tool/software: TINA-TI or Spice Models
Hi,
I'm trying to simulate the performance of LM5060 Controller and LM5050-1 connected in series using Orcad/Ppice, but I can't since I get problems of convergence as following report:
ERROR(ORPSIM-15138): Convergence problem in Transient Analysis at Time = 71.05E-21.
Time step = 71.05E-21, minimum allowable step size = 1.000E-18
I've varied the values of the simulation parameters but convergence problems still occur.
On the other hand, I've simulated LM5060 and LM5050-1 separately and both simulations perform correctly without any modifications on the simulation parameters.
Can somebody tell me how to simulate both devices together? Is it necessary to vary something concrete in the simulation parameters?
Thank you in advance.
