LM2596 Step Down DC-DC Buck Converter Adjustable Module - ADIY
Typically between 33µH and 100µH, depending on the desired output current.
Here is your complete guide to sourcing, installing, and simulating the LM2596 library in Proteus. proteus lm2596 library

): 1N5824 or equivalent fast-recovery diode (provides a feedback path for inductor current). Feedback Resistors ( LM2596 Step Down DC-DC Buck Converter Adjustable Module
Fixed versions have internal resistor dividers that set the output voltage. The adjustable version requires external resistors connected to the feedback pin. Both share the same basic pinout and external component requirements.
: Capable of driving a 3A load with excellent line and load regulation. Feedback Resistors ( Fixed versions have internal resistor
Connect the pin (Pin 2) to the cathode (striped side) of the Schottky diode D1cap D sub 1 and to one side of the inductor L1cap L sub 1 . Connect the anode of D1cap D sub 1 to Ground. Connect the other side of the inductor L1cap L sub 1 to your output rail. Place COUTcap C sub cap O cap U cap T end-sub between this output rail and Ground.
