Library For Proteus - Lm2596
Check the inductor's saturation current. In Proteus, if the inductor model has no current limit, it might simulate as a short. Add a series current limit property to the inductor, or use a virtual inductor from the ACTIVE library.
Proteus (by Labcenter Electronics) does include this component in its default libraries. Therefore, you must either: lm2596 library for proteus
To use the LM2596 in your project, you may need to download and import a third-party library. Follow these steps to install it: Check the inductor's saturation current
