MP1584EN ultra small DC-DC 3A power step-down adjustable module Buck Converter 24V turn 12v 9V 5V 3V

The MP1584EN ultra small DC-DC module is an adjustable step-down (buck) converter built around the MP1584EN regulator from Monolithic Power Systems. It converts a higher DC voltage, such as 24 V or 12 V, into a lower adjustable output like 12 V, 9 V, 5 V or 3.3 V, with up to 3 A output, on a board small enough to fit inside almost any project.

MP1584EN Specifications

• Regulator IC: MP1584EN step-down converter
• Input voltage: 4.5–28 V DC
• Output voltage: 0.8–20 V DC, adjustable with the on-board potentiometer
• Output current: up to 3 A maximum; lower continuous loads keep the board cooler
• Switching frequency: about 1 MHz (up to 1.5 MHz)
• Board size: about 22 × 17 mm

MP1584EN Applications

• Powering 5 V Arduino and ESP boards from a 12 V or 24 V supply
• Making a 3.3 V rail for ESP8266, ESP32 modules and sensors
• Drones, RC models and robots where space and weight matter
• Replacing hot linear regulators to save power
• Battery-powered and automotive DIY projects

What's in the Box

• 1 × MP1584EN adjustable step-down module

Tip: Set the output voltage with a multimeter before connecting your load: turn the potentiometer slowly while measuring the output. The input voltage must always be higher than the output you set, and the input must stay below 28 V.
