## Overview

The eBoot Mini MP1584EN is a high-performance DC-DC buck converter module delivering adjustable output voltage from 0.8V to 20V with a maximum 3A current and up to 92% efficiency. Its compact size and wide operating temperature range make it ideal for DIY electronics, mobile power, and sensitive device applications. The module features reliable overload protection to safeguard connected equipment and comes in a convenient 6-pack for versatile use.

## Description

Specifications: Input voltage: 4.5V to 28V Output voltage: 0.3V to 20V Output current: 3 A (maximum) Conversion efficiency: 92% (maximum) Output ripple: less than 30 mV Switching frequency: 1.5 MHz (highest), typically 1 MHz Operating temperature: -45 ℃ to 85 ℃ Size: 22 mm by 17 mm by 4 mm Application: DIY mobile power, monitor power supply, power buggies, camera power supply, car power, communications equipment supply, etc. Package includes: 6 x Mini MP1584EN DC to DC buck converter You can adjust the voltage by placing a multi-meter on the output, synchronously, using a screw driver to adjust a potentiometer. It can be minute adjustments to achieve a precise voltage. Kindly reminder These boards are adjustable current limiting, fixed 3A current limit. Please make sure that this module within its working range before using. Please don't output short circuit, otherwise the board would burn out. When setting the parameter, please make sure output voltage is stable before using the module to avoid any possible damage. Tips: Please check if the product package is intact before opening. Please check if the negative and positive terminals are accessed correctly before operating. The input voltage should not be over 28V to avoid damage.

Review: Excellent adjustable buck style voltage regulators.. don't get hot, provide a soild voltage feed with raises and falls that stay within 1 to 2 hundredths a volt.. give a fairly clean output voltage (still need a LC filter if you want very clean wave forms) provides 0.6 to 23 volts from my testing.. able to pull a constant 3.5 amps off it at 16.8v without it getting hot 2.5amps at 20volts gets warm but ok... 3amps at 20v will cook the coil in about 20 minutes.. at 12v I was able to pull a solid 4.2a off it for 2 hours and the temp never got above 97F, 4.5a at 12v smoked it in 7 minutes... If you cook the coil on it it does NOT allow full voltage to pass through (I have had some buck regs fail and allow full voltage to pass through for a few seconds.. I killed two of these intentionally to make sure that when it failed no voltage pass through and on neither one did that happen and that makes me VERY HAPPY. A failure acts like a breaker, it fails it fails and circuit is instantly broken.. I tested this with a O-scope and it had 0ms of full voltage seep when it failed..) These are incredibly cheap and excellent quality.. over preform and stay dang steady.. These are without a doubt the best cost to preformance ratio bucks you can buy... Bucks are not a place to skimp and buy as cheap as possible BECAUSE a failure on a buck that is supplying constant regulated voltage to high dollar electronics and fail and allow unregulated voltage to seep by for even a 1ms can damage sensitive to voltage electronics and ruin your day and make you wish you wouldn't have saved that 30 cents per piece.
Review: I got these to power a raspberry pi on my 3d printer. it was really simple to set it to 5.3v out on 24v in and it gets warm but not to a concerning level. voltage seems steady. Seems to be working great! cant wait to use the other 5 somewhere
