EBOOT MP1584EN DC-DC Buck Converter Module – 24-Pack, 4.5–28V In, 0.8–20V Out, 3A

Overview

Meet the EBOOT MP1584EN DC-DC buck converter module, a compact, dependable step-down solution designed for tight spaces and simple prototyping. The 22 x 17 x 4 mm board pairs a simple footprint with versatile power handling, ideal for hobbyists and light professional use.

Wide input and adjustable output

Designed to accommodate an input range of 4.5 to 28 V and an adjustable output from 0.8 to 20 V, this module lets you tailor voltage for a variety of devices without swapping parts. It supports up to 3 A of current, with real performance depending on load and input conditions.

Performance and efficiency

• Maximum current: 3 A; actual power depends on voltage and load
• Efficiency up to 92%, helping reduce heat during longer runs
• Output ripple under 30 mV for stable supply to sensitive components

Fast switching in a small package

• Switching frequency around 1 MHz in normal operation, up to 1.5 MHz peak
• Very compact footprint (22 mm x 17 mm x 4 mm) for crowded boards
• Wide operating temperature range from -45 to 85 degrees C

Usage tips and safety notes

To avoid possible issues, avoid very light loads (less than about 10% of output) and avoid running the module without load. Use proper heatsinking or ventilation in dense enclosures.

Getting started

Connect your supply within the specified range, adjust the output to the desired level within 0.8–20 V, and validate with a known load. Confirm stable voltage before connecting sensitive circuits.

Why it may fit your project

• Compact size supports small enclosures and compact breadboard setups
• Flexible input/output makes it suitable for various rail requirements
• Clear, low-noise output helps power microcontrollers and sensors

Note: Performance depends on the entire system; results vary with load, wiring, and heatsinking.
