MP1584 Adjustable Step Down Buck Converter

The MP1584 is a compact, high efficiency DC DC step down buck converter designed to reduce higher input voltages down to a stable, adjustable lower output. Its small footprint, high switching frequency, and strong current capability make it ideal for powering microcontrollers, sensors, and other electronics where efficiency and heat management matter.

This module is simple to use and widely trusted for DIY projects, prototyping, and embedded systems. The onboard potentiometer allows the output voltage to be easily adjusted, providing flexibility across a wide range of applications while maintaining excellent efficiency.

If you are looking for alternative power modules, you may also be interested in the LM2596 + LED Voltage Buck Step Down Converter Regulator for robust, lower frequency applications, or the XL6009 + LED Step Up Voltage Converter if your project requires boosting voltage instead of stepping it down.
