To get 5V: 5 = 1.23 × (1 + R2/R1) → R2/R1 = 3.06 → Choose R1=1kΩ, R2=3.06kΩ (use 3.3kΩ in simulation).
The LM2596 is a highly popular monolithic step-down (buck) switching regulator capable of driving a 3A load with excellent line and load regulation. It is a staple component in electronics projects requiring efficient voltage conversion, such as stepping down a 12V or 24V power supply to 5V or 3.3V for microcontrollers.
With the schematic fully wired, you can leverage Proteus’s native diagnostic tools to verify system performance before manufacturing. Running Interactive Simulations proteus lm2596 library
The LM2596 is a staple in the electronics world for step-down voltage regulation. When designing a PCB or simulating a circuit in Proteus, having a reliable library for this component is essential for accurate testing and footprint layout.
The simulation results show that the LM2596 library accurately models the behavior of the LM2596 IC. To get 5V: 5 = 1
