Output current: 3A max, please enhance cooling work when it is full load. When actual tested input 12V and output is 1.5A, no need to add other system. Enable function control: yes, low electric level will stop working when high electric level is working. High electric level is 2-5V, low electric level is 0V or so. Operating temperature: -40℃ - +85℃, industrial class, the higher the operation temperature is, and the smaller the output power is. Conversion efficiency: 97.5%, 6.5V to 5V, 0.7A Switch frequency: 500KHz Output ripple: 20 mV, 12V to 5V, 3A, 20M width Output over-voltage protection: no Temperature rising range at full load: 40℃ Static current: 0.85mA Voltage adjustment rate: ±0.5% Dynamic response speed: 5% 200uS Output short-circuit protection: yes, please don’t keep making it short-circuit. Output reverse connection protection: no Wiring method: connecting Output method: connecting or pins Connecting hole spacing: 2.54 mm Size: Approx. 20 x 11 x 5 mm/0.79 x 0.43 x 0.19 " Package includes: 12 x Mini 5v regulators Review: Incorrect voltage ratings for this board - This board's voltage regulator ic is marked dkgab which is NOT a 24v regulator, it's max voltage is 18v, so this not as advertised and is NOT going to work for my application! Give it more than 18v and it will fry quickly! Review: Not bad, but misleading functionality - I'm using this quite successfully to switch 12V down to 5V using the static 5V setting, and my multimeter reads it at 4.999V -- stellar accuracy. It's also CRAZY small -- it fits underneath and inside the pins of an Arduino Nano, as long as the nano is mounted on higher headers. The problem is that I spent a little bit more on this model versus others on false pretenses. Most of the other cards have a trace that you need to cut if you don't want to use the potentiometer, but this one leads you to believe you have to put solder on the "Adj" pad to turn the pot ON. I liked that because I hate slicing traces and knew I wanted a static output. It turns out, the pot is on by default, and I couldn't figure out a trace to cut to take it out of the circuit. Just soldering the 5V pad gave me 3V and change. Finally I took the sharp edge of a utility blade and pried the pot clean off the top of the board, and boom, now I'm getting 5V. Still 4 stars because the accuracy (at least with 12V in) is good, and prying the pot off isn't too hard. I'm just miffed I could have gone with a cheaper component. ## Features - 【Reliable & Nice Performance】: the voltage regulator module has high efficiency, ultra-compact size, high frequency, low ripple and stable working performance, widely applicable for fixing work: Synchronous rectification and the circuit conversion efficiency is as high as 97.5%. - 【High Quality Material】: Alinan buck converter is made with quality potentiometer and 3A current chip, high current shielding inductor and MLCC solid capacitor with long service life, High current shielding inductance, ultra-low internal resistance, maximize conversion efficiency, reduce heat generation, reliable and durable, bringing convenience in your life. - 【Easy to Use】: Integrated design allows port of the regulator board defaults to keep working mode and will be closed if it is at low electric level off, and with ultra-low quiescent current of 0.85 mA; It can be connected to the car battery without a extra switch, car female socket, cigarette lighter cord or the ACC power cord, convenient to use. The best thing about it is its tiny little footprint. - 【Mini Board, Maxi Performance】: The power input: DC 4.5 - 24V, adjustable range: 0.8 - 17V; Fixed output: 1.8V, 2.5V, 3.3V, 5V, 9V, 12V (can be chosen on the back); Max output current: 3A; If the actual test input is 12V and output is 1.5A, Size: Approx. 20 x 11 x 5 mm/0.79 x 0.43 x 0.19 ", no other system is required, very useful for small projects. - 【Adjustable and Fixed Voltage Output】: this buck converter allows you to get fixed output voltage by connecting the pot on the board, and you can adjust the fixed output voltage by potentiometer as you needed. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09MYNQLQB | | Best Sellers Rank | #1,175,730 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #5,361 in Power Converters | | Brand Name | Alinan | | Current Rating | 1.5 Amps, 3 Amps | | Customer Reviews | 2.9 2.9 out of 5 stars (5) | | Manufacturer | cwd | | Maximum Frequency | 500 KHz | | Minimum Frequency | 50 Hz | | Mounting Type | No Mounting Required | | Power Source | Battery Powered, Corded Electric | | UPC | 701715497634 | ## Product Details - **Brand:** Alinan - **Current Rating:** 1.5 Amps, 3 Amps - **Mounting Type:** No Mounting Required - **Power Source:** Battery Powered, Corded Electric - **UPC:** 701715497634 ## Images ![Alinan 12pcs 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 - Image 1](https://m.media-amazon.com/images/I/71WTngt-w7L.jpg) ![Alinan 12pcs 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 - Image 2](https://m.media-amazon.com/images/I/51FDxxJ0E0L.jpg) ![Alinan 12pcs 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 - Image 3](https://m.media-amazon.com/images/I/61qcDnyh09L.jpg) ![Alinan 12pcs 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 - Image 4](https://m.media-amazon.com/images/I/51SpSCcQgyL.jpg) ![Alinan 12pcs 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 - Image 5](https://m.media-amazon.com/images/I/51XIG7A3HAL.jpg) ## Customer Reviews ### ⭐ Incorrect voltage ratings for this board *by T***. on April 10, 2024* This board's voltage regulator ic is marked dkgab which is NOT a 24v regulator, it's max voltage is 18v, so this not as advertised and is NOT going to work for my application!

We require a stepdown from 19v (Milwaukee M18 battery pack) to 9v and it will not work. Have burned up 5 units thinking I was doing something wrong. ## Frequently Bought Together - 12pcs 5V DC Regulator Power Module Mini Buck Converter Voltage Reducer Adjustable DC to DC 4.5 - 24V 12V 24V to 5V 3A Volt Reduced Voltage Regulator Power Supply Transformer Power Step-Down Module - ESP-WROOM-32 ESP32 ESP-32S Development Board 2.4GHz Dual-Mode WiFi + Bluetooth Dual Cores Microcontroller Processor Integrated with Antenna RF AMP Filter AP STA Compatible with Arduino IDE (3PCS) - EDGELEC 120pcs Breadboard Jumper Wires 10cm 15cm 20cm 30cm 40cm 50cm 100cm Optional Arduino Wire Dupont Cable Assorted Kit Male to Female Male to Male Female to Female Multicolored Ribbon Cables --- ## 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.mx/products/404224586-alinan-12pcs-step-down-power-supply-module-mini-dc-dc](https://www.desertcart.mx/products/404224586-alinan-12pcs-step-down-power-supply-module-mini-dc-dc) --- *Product available on Desertcart Mexico* *Store origin: MX* *Last updated: 2026-05-25*
