They have done a great job so far, delivering stable performance without any issues. Given that they are buck converters, I cannot help but groan at the company name - but puns aside, they are excellent little boards. I would happily recommend them for projects where space is at a premium and you need reliable voltage regulation. ## Features - Input voltage: 4.5V to 28V - Output voltage: 0.8V to 20V - Output Current: 1.8 A typical (3.0 max) - Ripple Output Frequency: 340KHz - Ripple voltage: 30mV ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07DJYW6P3 | | Best Sellers Rank | #143,756 in Electronics ( See Top 100 in Electronics ) #1,424 in International Power Adapters | | Item model number | DC-DC step down module | | Manufacturer | DollaTek | | Package Dimensions | 11.8 x 8.6 x 1.4 cm; 20 g | ## Product Details - **Amperage:** 3 Amps - **Brand:** DollaTek - **Colour:** Green - **Compatible devices:** Laptops, Tablets, Smartphones, Handys - **Connector type:** DC power jack - **Included components:** 10x power Step-Down Adjustable Module - **Input voltage:** 24 Volts - **Number of Items:** 10 - **Special features:** Adjustable - **Wattage:** 10 watts ## Images ![DollaTek 10Pcs MP1584EN Ultra Small DC-DC 3A Power Step-Down Adjustable Module Buck Converter 24V to 12v 9V 5V 3V for Arduino - Image 1](https://m.media-amazon.com/images/I/61m1QCFq0rL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by D***R on 26 February 2025* prima en werkt zeer goed top ### ⭐⭐⭐⭐⭐ Review *by T***N on 13 August 2025* These DollaTek MP1584EN modules arrived quickly and are impressively small, which was perfect for my very tight solar panel case.

Sehr schön klein, dennoch aber noch lötbar ohne Lupe und gut einstellbar. Ausgabespannung nach Messung ist fast genau, bis auf ein paar Nuancen, aber das passt für meinen Bereich. ## Frequently Bought Together - DollaTek 10Pcs MP1584EN ultra Small DC-DC 3A power Step-Down Adjustable Module Buck Converter 24V To 12v 9V 5V 3V for Arduino - YOUMILE 10Pcs Step-Down Power Supply Module Mini DC-DC 12-24V To 5V 3A Voltage Buck Converter Adjustable 1.8V 2.5V 3.3V 5V 9V 12V --- ## 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.be/products/377820587-dollatek-10pcs-mp1584en-ultra-small-dc-dc-3a-power-step](https://www.desertcart.be/products/377820587-dollatek-10pcs-mp1584en-ultra-small-dc-dc-3a-power-step) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-04-22*
