Thread Summary

                The user encountered an analysis error when simulating the LM5085Q in LTspice. The issue was resolved by disabling the .uic option. The user also tried changing the Reltol setting from 0.001 to 0.0001, which did not resolve the error. The user's LTspice version was noted to be old, and they were advised to update to the latest version.

Hello All


I encountered an analysis error when I start the LM5085Q simulation. Show the simulation schematic and error below.


Try to change Reltol setting from 0.001 to 0.0001, no work.


Could you help to fix this problem?
