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 ## 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 | #95,500 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #355 in Power Converters | | Brand Name | DORHEA | | Current Rating | 3 A | | Customer Reviews | 4.6 4.6 out of 5 stars (41) | | Manufacturer | DORHEA | | Maximum Frequency | 1 MHz | | Minimum Frequency | 50 hertz | | Model | U13537-1 | | Mounting Type | Portable | | Part Number | U13537-1 | | Power Source | Dc Power Supply | | UPC | 701715434004 | | Unit Count | 10 Count | ## Product Details - **Brand:** DORHEA - **Current Rating:** 3 A - **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) ## Available Options This product comes in different **Color** options. ## Frequently Bought Together - 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 - OCR 20PCS 2.54mm Breakaway PCB Board 40Pin Male and Female Header Connector for Arduino Shield - KOOBOOK 5Pcs DRV8833 Motor Drive Module 1.5A Dual H Bridge DC Gear Motor Driver Controller Board --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/220433509-dorhea-10pcs-mp1584en-3a-mini-step-down-buck-converter-dc](https://www.desertcart.hk/products/220433509-dorhea-10pcs-mp1584en-3a-mini-step-down-buck-converter-dc) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-08-18*
