Description

The MP1584 DC-DC Buck Converter is a high-efficiency step-down voltage regulator module that allows users to step down input voltages from 4.5V–28V to a selectable lower output voltage (0.8V–20V) with up to 3A output current. Its compact design and adjustable potentiometer make it ideal for powering Arduino, ESP32, Raspberry Pi, sensors, and other modules requiring stable voltage. The module also features overcurrent, thermal, and short-circuit protection for safe operation.
