Go to System -> Set Simulation Options and adjust the SPICE options to a higher tolerance, or simplify the other components in your circuit while testing the power delivery stage. Conclusion
While Proteus is excellent for microcontroller + power integration, dedicated SPICE tools like LTspice have accurate LM2596 models from Texas Instruments. Simulate there, then use Proteus for PCB layout.

Select the Virtual Instruments Mode from the left toolbar. Place a DC Voltmeter across the input source and another across the output load. Configure Input: Set your DC source block to 12V.
Connect OUTPUT (Pin 2) to your inductor (e.g., 33µH).
Utilize the built-in oscilloscope to measure voltage fluctuations and optimize your smoothing capacitors. “Component not found in library” Go to System

Proteus comes pre-loaded with hundreds of components, from basic resistors and op-amps to complex microcontrollers like the PIC and Arduino. However, the default POWER or ANALOG libraries often miss modern, high-current switching regulators.
Connect the other side of the inductor to the FEEDBACK (Pin 4) . This creates the voltage regulation loop. Place the 330µF output capacitor between this node and Ground to smooth the DC output. VOUT=VREF(1+R2R1)cap V sub cap O cap U cap

The LM2596 is a highly popular step-down (buck) voltage regulator capable of driving a 3A load with excellent line and load regulation. It is a staple in embedded systems and power supply designs. However, the default library in Labcenter Electronics Proteus does not include a simulation model for the LM2596. To test your buck converter circuits before prototyping, you must manually install a third-party LM2596 Proteus library.
To create a functional buck converter circuit around the LM2596, you must place the following peripheral components:
One of Proteus’s superpowers is combining analog power supplies with digital microcontrollers (Arduino, PIC, 8051).
The LM2596 is a monolithic switching regulator capable of driving a 3A load with excellent line and load regulation. It is widely available in fixed output voltages (3.3V, 5V, 12V) and an adjustable version.
