For Vout = 5V, choose R1 = 1kΩ and R2 = 3.1kΩ (use 3kΩ in practice). lm2596 proteus library

Proteus does not always include the LM2596 in its default installation. Adding a third-party library enables:

Use the in Proteus to measure output voltage ripple. Connect a probe to the output and look at the waveform using the graph-based simulation (press F8). The ripple at 150 kHz should be low if the output capacitor is properly chosen.

The is a popular step-down (buck) switching voltage regulator from Texas Instruments. It belongs to the SIMPLE SWITCHER® family and can drive a load up to 3A with excellent line and load regulation. It operates at a fixed switching frequency of 150 kHz. The device is available in multiple fixed output voltage versions: 3.3V, 5V, 12V, and an adjustable output version (LM2596-ADJ). For Vout = 5V, choose R1 = 1kΩ and R2 = 3

Double-check your diode orientation. If the Schottky diode is connected backward, it creates a direct short circuit to the ground when the internal switch turns on. Conclusion
