DC/DC Buck Converter Module 0.8V-20V Adjustable Step-Down 3A MP1584

The DC/DC Buck Converter Module is a compact, high-efficiency step-down voltage regulator built around the MP1584 switching controller. It accepts an input voltage between 4.5V and 28V and delivers a fully adjustable output from 0.8V to 20V at up to 3A - making it one of the most versatile power regulation modules available for electronics projects, prototyping boards, and embedded systems.

The onboard trimpot lets you dial in exactly the output voltage your circuit needs, while the MP1584's 1.5MHz switching frequency keeps output ripple below 30mV. At just 22mm x 17mm x 4mm, it fits inside battery packs, robotics chassis, 3D printer electronics bays, and custom enclosures with ease.

Key Features
