to save your LM2596 circuit layout and reuse it in future designs without re-drawing it. Troubleshooting Tips Library Not Showing : Ensure you placed the files in the Data\Library folder, not just the root installation folder. Simulation Errors

While Proteus comes with thousands of built-in components, specific integrated modules like the LM2596 buck converter often require for high-fidelity simulation.

Ensure you have the LM2596.LIB and LM2596.IDX files.
