: Supports an input voltage range from 3V to 40V and offers an adjustable output from 1.5V to 35V .
Ensure you used a fast Schottky diode. Standard diodes (like the 1N4007) are too slow for switching frequencies and will fail the simulation. 3. "No Simulator Model Found"
For the LM2596 (TO-220 package), you need 5 pins: lm2596 proteus library
The LM2596 Proteus library is a powerful tool for designers who want to create and simulate DC-DC converter circuits using the LM2596 IC. The library provides pre-built models, simulation capabilities, and adjustable parameters, which make it easy to design and test different scenarios. By using the LM2596 Proteus library, designers can save time and effort, improve accuracy, and increase productivity. The library has a wide range of applications in electronic design, including power supply design, analog circuit design, and embedded system design. Overall, the LM2596 Proteus library is a valuable resource for anyone working with DC-DC converter circuits.

If you feed 12V into a fixed 5V LM2596 model, the output voltmeter should stabilize closely at 5.0V.
Try modifying the adjustable version for 3.3V or 12V output. Simulate load steps and observe the feedback response. Then, move to PCB layout in Proteus ARES and build your physical prototype.
