Mini MP1584 DC-DC 3A Adjustable Buck Converter Module

The Mini MP1584 DC-DC 3A Adjustable Buck Converter Module is a compact and high-efficiency step-down power supply solution designed for applications where space and weight are critical. Built around the MP1584EN high-frequency switching regulator with an integrated high-voltage power MOSFET, this module efficiently converts higher DC input voltages into lower, stable output voltages.

It supports an input voltage range from 4.5V to 28V and provides an adjustable output voltage from 0.8V to 20V. The output voltage can be precisely tuned using the onboard multi-turn potentiometer, allowing flexibility for powering a wide variety of devices. The module delivers a typical output current of 1.8A and can reach up to 3A maximum with proper heat dissipation.

Thanks to its high switching frequency design, the MP1584 enables the use of small ceramic capacitors while maintaining excellent stability and low ripple. It features internal soft-start functionality to reduce inrush current during startup, helping to protect both the module and connected loads. Built-in thermal shutdown and under-voltage lockout (UVLO) further enhance reliability by preventing operation under unsafe temperature or voltage conditions. The internally set current limit eliminates the need for an external current sensing resistor, simplifying circuit design.

Its ultra-small footprint and lightweight construction make it ideal for compact embedded systems and portable electronics. The module is widely used in RC cars, airplanes, quadcopters, robotics systems, and various DIY electronics projects. It is also suitable as a breadboard power supply, for manual speed control of small DC motors, and as a Universal Battery Elimination Circuit (UBEC) for 2S to 6S LiPo battery packs. Additionally, it can serve as a stable receiver or servo power supply and as a regulated power source for communication and mobile equipment.

The Mini MP1584 Buck Converter is a reliable and efficient voltage regulation solution for developers working with platforms such as 8051, AVR, ARM, PIC, Arduino, Raspberry Pi, and other microcontroller-based systems where precise, adjustable DC voltage conversion is required
