If your Proteus version lacks LM2596:

  • Restart Proteus

    • Common simulation issues:

    Some advanced LM2596 libraries include thermal pins. Connect a heat sink component and watch how junction temperature rises at 3A continuous load.

    Proteus includes LM2596 in the Power Electronics library:
