Connect to an Inductor (usually 33µH to 100µH) and a Schottky diode (1N5822). Ground (Pin 3 & 5): Connect to common ground. After successful installation, you can add the LM2596

The LM2596 belongs to Texas Instruments' SIMPLE SWITCHER® family. It is capable of driving a 3A load with excellent line and load regulation, available in fixed output voltages (3.3V, 5V, 12V) and an adjustable version. Its high switching frequency of 150 kHz allows for the use of smaller external components, making it ideal for compact buck converter designs.
