You can find the necessary library files (typically in a .zip or .rar format) from trusted hobbyist sites like The Engineering Projects or GitHub . Ensure your download includes these specific file types: : The component data. .IDX : The index file for the component.
Now, fire up Proteus, place that LM2596-ADJ from your library, design a 12V to 3.3V converter, and watch your inductor current waveform. Happy simulating!
The LM2596 requires a catch diode to carry the load current when the switch is off.
