There is no official, updated LM2596 library for Proteus from Labcenter.
The ones floating on blogs are:

If you actually need simulation of the LM2596's switching behavior, Proteus is not great. Use: There is no official, updated LM2596 library for
Do not just trust the library exists. Simulate a working buck converter. If you actually need simulation of the LM2596's
The LM2596 is a widely used buck (step-down) switching regulator IC by Texas Instruments (originally National Semiconductor). It’s popular in hobby and professional designs for converting higher DC voltages down to a regulated lower DC voltage (commonly 3.3V, 5V, 12V) with high efficiency, using an external inductor, diode, input/output capacitors, and feedback resistors.
Once you have downloaded the updated files (usually a .LIB and .IDX), follow these steps:
LM2596.LIB and LM2596.IDX into the LIBRARY folder.LM2596.Proteus (by Labcenter Electronics) is a schematic capture and simulation suite used for electronic design and for running circuit-level simulations, including mixed-mode and SPICE-like behavior. A Proteus library (component model) for the LM2596 lets you place the regulator in schematics and simulate circuit behavior. An accurate, updated library should include:
