Verify the grounding configuration of the feedback loop. For adjustable models, check the resistor divider network ratio ( R1cap R sub 1 R2cap R sub 2 ) using the standard reference formula:
The simulation waveforms show the input voltage, output voltage, and inductor current:

Sites like Ultra Librarian or SamacSys offer CAD models that can be converted or imported directly into Proteus. Step-by-Step Installation Guide
Press the button in the bottom-left corner of the Proteus interface. If you downloaded a simulation-ready model, the DC Voltmeter will display a steady, stepped-down voltage (typically lm2596 library for proteus extra quality

Once you have a trustworthy LM2596 library, you can confidently simulate:

If you need help optimizing your power supply design, tell me: What is your ?
Websites like The Engineering Projects frequently publish free, high-quality multi-device libraries optimized for simulation.
Create a new project in Proteus and select the LM2596 library from the list of available libraries.
Remember that while the LM2596 is rated for 3A, Proteus simulations might not always flag over-current issues unless the library model is specifically programmed for it. Step-by-Step Installation Guide Press the button in the
