Hi Shubham,

I do not see the error you have. I did get something about your marker settings. When using this model, you need to place 3 markers in the schematic.

See the attached project archive: led_driver_al8860-2022-04-29T17-26.zip

Here's the sim resultt:

Hi Zhu,

i tried simulation it worked but im getting some converge error for U4 and U6 please see below I don't know how to fix this error, please help me on the same.

ERROR(ORPSIM-15660): These devices failed to converge
X_U4.DLED1
X_U6.DSD1
ERROR(ORPSIM-15659): Discontinuing simulation due to convergence problem
INFO(ORPROBE-3185): Simulation paused

Thanks,

Shubham

Hi Shubham,

You can try relaxing certain tolerances which may help. You can also let PSpice try that for you by using auto convergence. See the attached archive.

Thanks,
JC
