MP1584EN ultra small DC-DC 3A step-down Regulator Module 24V to 12V, 9V, 5V, 3V for Arduino

Description

The MP1584EN is a step-down (buck) voltage regulator that reduces the input voltage to a lower output voltage. It is ideal for powering electronic projects that require a regulated voltage.

Input: 4.5V – 28V
Output: 0.8V – 20V
Maximum output current: 3A
Efficiency: >96%

What it’s used for: The MP1584EN is particularly useful for powering Arduino and maker projects that require a regulated voltage. For example, it can be used to power LEDs, motors, or other electronic components with a specific voltage. It can also be used to create a regulated power supply for an Arduino project, allowing the output voltage to be adjusted to meet the specific needs of the project.

Tutorial: How to use DC-DC MP1584EN
The MP1584EN is an ideal step-down (buck) voltage converter for reducing supply voltage to a lower voltage. This component is particularly useful for Arduino and maker projects that require regulated power.

What you need: Arduino or microcontroller
Head-to-head connections (male-male)
24V power source

Steps: Connect the 24V power source to the MP1584EN. Set the switch to 12V, 9V, 5V, or 3V as needed for the project. Connect the MP1584EN to the Arduino using male-male connections. Check the output voltage with a multimeter. If necessary, further adjust the switch to achieve the desired voltage.

Mini-project: Create a controllable LED lamp powered by the MP1584EN. Set the module to provide 5V and use an Arduino PWM controller to vary the brightness.

Common errors: Incorrectly setting the output voltage, connecting the polarity incorrectly, using a power source that exceeds the module’s maximum limits (3A), ignoring the importance of heat dissipation.

Recommended accessories: Filtering resistors and capacitors, 40mm fan, digital multimeter, AC-DC 24V power supply
