LM5158: simulation running time less than configure

Part Number: LM5158


I want use LM5158 to output +/- 75V/25mA voltage from a input voltage 3.0V~5V. for evaluation the design, I do some simulation and try to evaluate the performance. however, the simulation is always slowly and stop simulation than I configured. is there any one in product line help to find root cause? thanks.




  • Hi Bill,

    Thank you for using E2E forums, I am a bit confused by your question, could you elaborate what do you mean by "is there any one in product line help to find root cause?"

    Thank you



  • Hi, Haroon

     please refer below figure. I want simulation running ~30ms. but the simulation just running ~2ms and then I just get a ramp curve and could not check the stability output. the second issue is the simulation is very very slowly. do you have any idea to reduce simulate time. 



  • Hi Bill,

    The simulation time can be reduced by making the system simpler but I guess apart from that nothing much can be done about that.

    Regarding the 2ms running and stopping, is there an error you are getting or warning of some sort?
