Are you designing for a output (3.3V, 5V, 12V) or an adjustable output?
Search GitHub for lm2596 proteus . You will find several open-source libraries. For example, All-In-One-Proteus-Library by ProteusLibrary on GitHub contains thousands of components, including voltage regulators.

If you cannot find or install the LM2596 library, here are workarounds:
Observe how the switching frequency affects output ripple. Are you designing for a output (3
If you found a ready-made library (a .zip or .rar file containing .LIB, .IDX, .MODEL files), follow these steps to install it.
: High-frequency switching simulations can cause CPU spikes in Proteus. If your simulation drags, try increasing the "timestep" in the system simulation settings. : High-frequency switching simulations can cause CPU spikes
Place a across the input capacitor and another across the output capacitor.
to the output, and hit "Play." If installed correctly, you’ll see that satisfying 5V reading on your virtual screen. Troubleshooting the Plot Twists
Add the input capacitor (C1), output capacitor (C2), inductor (L1), and Schottky diode (D1). For the LM2596-ADJ version, also add the feedback resistors (R1 and R2).
