Always cross-check critical simulations with manufacturer tools (TI’s WEBENCH or LTspice’s LM2596 model). Use the Proteus library for system-level integration tests, not for absolute ripple or efficiency numbers.

To find the LM2596 library for Proteus, you can try the following options:
The LM2596 series are monolithic integrated circuits that provide all the active functions for a step-down switching regulator. It is capable of driving a 3A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V, and an adjustable output version. Because it operates at a switching frequency of 150 kHz, it allows for smaller sized filter components than what would be needed with lower frequency switching regulators.

If you’re a hardware designer or an electronics engineering student, you’ve likely encountered the – a popular step-down (buck) switching voltage regulator. Simulating a circuit containing this IC before soldering is a wise practice. However, Proteus ISIS does not include the LM2596 in its default component library. This is where a custom LM2596 Library for Proteus becomes essential.
If you are unable to find a pre-existing library, you may be able to model one using the "Voltage Controlled Switch" and other components within Proteus itself. It is capable of driving a 3A load
Here’s how you’d set up a simulation in Proteus after installing the library:
