LM2596 DC-DC Buck Converter Step-Down Power Module
$1
The LM2596 Buck Converter Module is a compact, efficient, and adjustable DC-DC step-down voltage regulator ideal for powering microcontrollers, sensors, LED strips, and other electronics from higher voltage sources.
This LM2596 step-down power module is based on the LM2596S switching regulator IC, allowing you to convert higher input voltages (4V–40V) down to a lower, stable output (1.25V–37V) with high efficiency.
Equipped with a multi-turn potentiometer, it enables fine voltage adjustment and delivers up to 2A continuous current (with proper heatsinking). It’s ideal for powering Arduino, ESP32, Raspberry Pi, sensors, motors, and more.
Its onboard components include a rectifier diode, filter capacitor, and inductor, ensuring a clean, ripple-free DC output.
Key Features:
✅ Input Voltage: 4V – 40V DC
✅ Output Voltage: 1.25V – 37V DC (Adjustable)
✅ Output Current: Up to 2A (peak 3A with heatsink)
