The LM2596 is a DC-DC buck converter IC (step-down regulator) that efficiently reduces a higher DC voltage to a lower DC voltage while providing high current output. It is widely used in power supply modules for Arduino, ESP32, Raspberry Pi, robotics, and battery charging circuits.
🔹 Details and Explanation
Type: Buck (step-down) voltage regulator IC
Input Voltage Range: 4.5V – 40V
Output Voltage Range: 1.23V – 37V (adjustable using a potentiometer in modules)
Output Current: Up to 3A continuous (with heat sinking)
Efficiency: Around 80–90% (much better than linear regulators like 7805)
Switching Frequency: ~150 kHz (high frequency reduces inductor size)
🔹 Working Principle
The LM2596 uses a switching regulator mechanism:
It rapidly switches a transistor ON/OFF and uses an inductor, diode, and capacitor to smooth the output.
Unlike linear regulators (which waste energy as heat), the LM2596 efficiently transfers power, giving higher efficiency.
By adjusting the feedback resistor (or onboard potentiometer in modules), the output voltage can be set to a desired level.
🔹 Typical Module Pins
IN+ : Positive input voltage (connect to power source)
IN- : Ground of input supply
OUT+ : Positive regulated output voltage
OUT- : Ground of output
🔹 Applications
Power supply for Arduino, ESP, and sensors
