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: Worked as advertised. - Works great. Cracks after a year or so. Will buy again. Review: Tiny Bucks - I've been using these tiny buck converters as inline cable components. I shrink wrap them in the supply cable, and they don't need to be mounted in the chassis of the supply device. The screw adjuster is quite sensitive. ## 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B089GV88DK | | Best Sellers Rank | #167,504 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #720 in Power Converters | | Brand | DORHEA | | Brand Name | DORHEA | | Current Rating | 3 A | | Customer Reviews | 4.6 out of 5 stars 41 Reviews | | Manufacturer | DORHEA | | Maximum Frequency | 1 MHz | | Minimum Frequency | 50 hertz | | Model | U13537-1 | | Mounting Type | Portable | | Number of Items | 10 | | Part Number | U13537-1 | | Power Source | Dc Power Supply | | UPC | 701715434004 | | Unit Count | 10 Count | ## Product Details - **Brand:** DORHEA - **Current Rating:** 3 Amps - **Mounting Type:** Portable - **Number of Items:** 10 - **Power Source:** Dc Power Supply ## Images ![Dorhea 10PCS MP1584EN 3A Mini Step Down Buck Converter DC-DC 24V to 12V 9V 5V 3V Adjustable Step Down Module Replace LM2596 Compatible with Raspberry Pi Robort Parts DIY Kit - Image 1](https://m.media-amazon.com/images/I/71WsLjK1JPL.jpg) ![Dorhea 10PCS MP1584EN 3A Mini Step Down Buck Converter DC-DC 24V to 12V 9V 5V 3V Adjustable Step Down Module Replace LM2596 Compatible with Raspberry Pi Robort Parts DIY Kit - Image 2](https://m.media-amazon.com/images/I/6137eroglCL.jpg) ![Dorhea 10PCS MP1584EN 3A Mini Step Down Buck Converter DC-DC 24V to 12V 9V 5V 3V Adjustable Step Down Module Replace LM2596 Compatible with Raspberry Pi Robort Parts DIY Kit - Image 3](https://m.media-amazon.com/images/I/51pBgRDzorL.jpg) ![Dorhea 10PCS MP1584EN 3A Mini Step Down Buck Converter DC-DC 24V to 12V 9V 5V 3V Adjustable Step Down Module Replace LM2596 Compatible with Raspberry Pi Robort Parts DIY Kit - Image 4](https://m.media-amazon.com/images/I/519JY8y8bdL.jpg) ![Dorhea 10PCS MP1584EN 3A Mini Step Down Buck Converter DC-DC 24V to 12V 9V 5V 3V Adjustable Step Down Module Replace LM2596 Compatible with Raspberry Pi Robort Parts DIY Kit - Image 5](https://m.media-amazon.com/images/I/51nS5QSAwzL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked as advertised. *by K***N on June 13, 2023* Works great.
