Description
The LM2596 DC-DC Buck Converter Adjustable Step-Down Power Supply Module is a highly efficient voltage regulator designed to convert a higher DC input voltage to a lower adjustable DC output voltage. Based on the popular LM2596 switching regulator IC, this module offers high efficiency (up to ~90%) and can deliver output currents up to 3A with proper cooling.
It is widely used in Arduino, ESP8266, ESP32, robotics, battery-powered systems, LED drivers, and DIY power supply projects. The onboard multi-turn potentiometer allows precise output voltage adjustment, making it ideal for stable and reliable power management.
