Access to predefined outputs (3.3V, 5V, 12V) alongside the flexible adjustable version.

If you are expanding this simulation into a full hardware layout, consider looking into the documentation for the Texas Instruments LM2596 Datasheet to study thermal layout guidelines, or review the Labcenter Electronics Proteus Simulation Guide to master advanced SPICE configuration settings.

Are you designing a or using a pre-made breakout module ?

VOUT=VREF(1+R2R1)cap V sub cap O cap U cap T end-sub equals cap V sub cap R cap E cap F end-sub open paren 1 plus the fraction with numerator cap R sub 2 and denominator cap R sub 1 end-fraction close paren (Where VREFcap V sub cap R cap E cap F end-sub is internally set to 1.23V. To achieve a 5V output, use , or a standard resistor). Simulating the Circuit in Proteus

The updated library, released in Q3/Q4 of 2024 (and refined in early 2025), addresses the above issues head-on. Here is the technical changelog:

I am actively working on V2.1 which will include a thermal shutdown flag.

Every component in the library comes pre-mapped to its correct footprint (TO-220 through-hole and TO-263 SMD) with updated 3D visualization files for precise mechanical clearance checks. How to Install the Updated LM2596 Library in Proteus

The download usually comes as a .zip or .rar file. Extract it to reveal two primary files: .LIB (The component's graphical and simulation model) .IDX (The index file that helps Proteus categorize it) 📂 Step 2: Install Files into Proteus

Adding the updated LM2596 library to your Proteus installation requires manual placement of the library files. Follow these steps to complete the integration: Step 1: Download the Library Files
