## Overview

The Dorhea MP1584EN 10-pack mini step-down buck converters offer a compact, efficient solution for converting 4.5V-28V input down to a finely adjustable 0.8V-20V output at up to 3A current. With 92% max efficiency and low ripple (<30mV), these modules are perfect for space- and weight-sensitive applications such as drones, Raspberry Pi projects, and vehicle electronics. Their ultra-small size and versatility make them a must-have for DIY enthusiasts and professionals seeking reliable, customizable power regulation.

## Description

Specifications: Input Voltage: 4.5V to 28V Output Voltage: 0.8V to 20V Output Current: 3A (Max) Conversion efficiency: 92% (Highest) Output Ripple: less than 30mV Switching frequency: 1.5MHz (highest) typically 1MHz Operating Temperature: -45 ℃ to 85 ℃ Module property: non-isolated buck module Mini MP1584EN DC-DC BUCK Adjustable Step Down Module Effect Higher Than LM2596 Step Down Power Module DC-DC 3A Adjustable Step Down LM2596 Ultra-Small Size Ultra-Small Size Step Down Power Module DC-DC 3A Adjustable Step Down Module LM2596 Application: DIY mobile power supply, monitoring power supply, children's car power supply, camera power supply, vehicle power supply, communication equipment power supply, all kinds of occasions (such as aircraft model) that have strict requirements on volume and weight. Note: This is buck converter. Only used to lower voltage, not to raise voltage, so the output voltage should be lower than the input voltage. If the output voltage is always equal to the input voltage. Please first turn the potentiometer clockwise more than 10 laps. Please make sure that this module is within its working range before using. Do not use without load or light load (less than 10% of output power) or connect too much things on one module. Package included: 10 X MP1584EN DC-DC Buck Converter

Review: Bought 10 of these and every one of them actually worked ! - Bought three different styles of step down regulators in last order . The entire lots of the first two types were rejected as defective and completely non functional . These little 5v step down regulators however work fine . Out of 10 units the output voltage from the same source (battery) ranged from 5.07 thru 5.21 volts . There is some variation in output voltage but .14vdc total spread is not fantastic but also not terrible either . Can't speak for longevity , noise , ripple or current capacity at this point . PCB's appear well soldered , can't complain for the price these days !
Review: 50% defect rate!! - High defect rate in these converters. Approximately 50% of the boards I tested were defective and could not output a suitable voltage in line with the description (Example 12volts in, could only get 1.5 to 2v out). Many had potentiometers that were seemed to 'jump around' and couldn't hold a consistent voltage. They were shipped in regular polyethylene bags without anti-static packaging. These seem cheap and a good value, until you realize you've wasted time with bad boards and have to sort the bad from good. Additionally, the boards were of inconsistent dimensions--they came with 2 different widths. this made packaging them into a project more challenging. The only reason I kept these were I ran out of time.

## Features

- Mini MP1584EN DC-DC buck adjustable step down module.
- Input voltage: 4.5V to 28V; Output voltage: 0.8V to 20V adjustable, Output current: 3A (maximum), less than 2.5A, Conversion Efficiency: 92% Max, Output ripple: Less than 30mV, Switching Frequency: 1.5MHz Max, 1MHz TYP.
- 1.0MHz Switching Frequency, <30mV ripple (no load), MP1584 IC.
- Smaller size just like the size of a coin, but it's only 2g, much lighter than the coin. So it's really a perfect solution for projects that have strict requirements on product volume and weight, such as aviation model.
- Wide Range of Applications: DIY mobile power supply, monitoring power supply, camera power supply, vehicle power supply, communication equipment power supply etc.
