The library is not typically included by default. You can find it on several simulation community websites:
Now, fire up Proteus, place that LM2596-ADJ from your library, design a 12V to 3.3V converter, and watch your inductor current waveform. Happy simulating!
Adding new components to Labcenter Electronics Proteus is a straightforward process. Follow these steps to update your database: Step 1: Download the Library Files proteus lm2596 library
A critical point to understand: The LM2596 is not natively supported for simulation in Proteus or other mainstream tools like MultiSIM. The component symbol you create is primarily for schematic capture and PCB layout, not for behavioral simulation.

If you get a model error, the library file might not have been installed in the correct folder, or you may be missing a .DLL co-simulation file. Conclusion
Are you designing for a (like 5V) or an adjustable setup ? Do you plan to generate a PCB layout from this simulation?
