Package Include: 2pcs Mini MP1584EN DC-DC Step-Down Converter Note: You can get a precise output voltage by placing a multimeter on the output and using a screwdriver to adjust the potentiometer slightly. Review: Seems to work, don't use without a load - Seems to be working after my first test. However, they weren't kidding that you should not have it attached to input power without a load. I let it set for a minute or two before checking the voltage again, nothing was connected to the output power, and placing the multimeter probes on the output leads burned it up. Review: Buckconverter cannot be adjusted. - The buckconverter i received, unable to find the potentiometer to adjust voltage. i am looking for 12V/5V. kindly advise asap. ## Features - Mini 3A DC-DC Step-down power module, suitable for aviation model power supply, DIY mobile power supply, monitoring power supply, four-wheel-drive power supply, communication equipment power supply, etc. - Wide Input Voltage Range: 4.5V to 28V, can be used as voltage regulator 24V/12V/9V to 12V/5V/3.3V etc. - Output Voltage: 0.8V to 20V adjustable, 3A (max), Transfer Efficiency up to 96%. - Working Temperature: -45 to 85 degrees Celsius, Size: 22x17x4mm.

However, they weren't kidding that you should not have it attached to input power without a load. I let it set for a minute or two before checking the voltage again, nothing was connected to the output power, and placing the multimeter probes on the output leads burned it up. ### ⭐ Buckconverter cannot be adjusted. *by S***. on 18 August 2026* The buckconverter i received, unable to find the potentiometer to adjust voltage. i am looking for 12V/5V. kindly advise asap. ### ⭐⭐⭐⭐⭐ Very small and works great. *by J***D on 22 January 2025* Product works great. I was able to regulate 12V to 3.3V. The product was missing any type of footprint dimensions. I've included picture of the footprint with pin spacing dimensions which seems to work for PCB design. ## Frequently Bought Together - DZS Elec 2pcs MP1584EN Mini 3A DC-DC Buck Converter 4.5V-28V to 0.8V-20V Adjustable Voltage Regulator 24V/12V/9V to 12V/5V/3.3V Step-Down Power Module - Bolsen 5pcs/lot Rotary Encoder,Code switch/EC11/ Audio Digital Potentiometer,with Switch,5Pin, Handle Length 20mm - HiLetgo 3pcs Nano V3.0 ATmega328P CH340G 5V 16M Mini USB Micro Controller Board Development Board with PIN Headers Pin Unsoldered --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/386554138-2pcs-mp1584en-mini-3a-dc-dc-buck-converter-4-5v](https://www.desertcart.kr/products/386554138-2pcs-mp1584en-mini-3a-dc-dc-buck-converter-4-5v) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-09-14*
