Designed with a durable SANYO solid-state capacitor and a thickened circuit board, it ensures reliable performance while effectively filtering out high-frequency noise. Ideal for DIY enthusiasts and professionals alike, this module is easy to install with its two wire connection mode. ## Description Specification: Type: LM2596S DC-DC Buck Converter Input Voltage: 3V-35V Output Voltage: 1.25V-35V Output Current: 3A Max Transfer Efficiency: 92% Max Output Ripple: Less than 30mV Switch Frequency: 65KHz Work Temperature: -45 to +85 degree Celsius Size: 43x21x14mm (LxWxH) Quantity: 2pcs Tips: 1. Input and output cannot be reversed, or it will burn the module. 2. Input voltage much be more than 1.5V higher than output voltage. Can not used to boost voltage. 3. After wire connection, first to turn a dozen times, then adjust the voltage by anticlockwise rotation. 4. It is recommended to use within 2.5A current for long time work, and need to add heat sink if the current exceeds 2A(output above 10W). Wire Connection: 1. Solder, weld the power cord directly to the input (output) port. 2. Welding Pin, can insert the pin with lead wire or insert into PCB, or welding on the PCB directly with pin. ## Features - Input Voltage: DC 3V-35V, Output Voltage: DC 1.25V-35V (continuously adjustable), high effeciency, max output current up to 3A. - Adopting SANYO solid-state capacitor, 36u thickened circuit board, high Q value large power inductance, with LED indicator. - High precision potentiometer, factory default is approx 18V. Turn the potentiometer counterclockwise 1 cycle, it may step-down approx 1V voltage. - 0.1uF high frequency bypass capacitor, can effectively filter out high frequency noise. - Two Wire Connection Mode: Solder and Welding Pin. ## Product Details - **Brand:** Maxmoral - **Power Source:** Battery Powered - **Mounting Type:** PCB Mount - **Current Rating:** 3 Amps - **Item Weight:** 1.58 Ounces ## Images ![2pcs DC-DC Buck Converter Power Module 3A Adjustable Step-Down LM2596 Voltage Regulator 24V to 12V 5V 3V - Image 1](https://m.media-amazon.com/images/I/71XjQOBpkrL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked Perfectly *by I***A on October 13, 2021* Used this to step down a li-Ion battery pack to 3.05v for a wireless guitar pack that previously chewed through 2xAA batteries. Board is a little taller than I had hoped, but it still fit for my use case. Little light in the board even gave me good insight as to the charge state of the battery. ### ⭐⭐⭐⭐⭐ Worked perfect *by D***D on April 15, 2024* worked perfect to change the voltage for a PC Fan. 24 volts to 12 volts. ### ⭐⭐⭐⭐ Better Instructions *by M***T on July 31, 2023* I think some of these are being returned due to poor instructions. I purchased these to run 12v fans on a 24v supply and so far the one is working great. (Haven't wired up the second yet). I'll come back and update this review if there's any issues or premature failure."After wire connection, first to turn a dozen times, then adjust the voltage by anticlockwise rotation."Sooooooo turn which direction a dozen times?I'm far from an electronics guru and this took me a bit to figure out based off other reviews so hopefully this helps.Turning clockwise - increases output voltageTurning counter/anti-clockwise - decreases output voltageThere's a LOT of adjustment in the potentiometer that simply will do nothing. Ignore the instructions - if you fire it up and the output voltage is the same as your supply, just keep turning counter clockwise until it starts going down. If you hear a clicking sound coming from the potentiometer it means it's bottomed out (try not to do this I'm guessing it's bad for it). I finally figured this out after cranking it counter clockwise for what felt like 40 turns and it started clicking. Then noticed my output voltage finally changed from 23.3 to basically zero. ## Frequently Bought Together - Maxmoral 2pcs DC-DC Buck Converter Power Module 3A Adjustable Step-Down LM2596 Voltage Regulator 24V to 12V 5V 3V - Noctua NF-A4x10 FLX, Premium Quiet Fan, 3-Pin (40x10mm, Brown) - Noctua NF-A4x20 FLX Computer Case Fan - Computer Cooling Components (Computer Case, Fan, 4 cm, 3700 RPM, 5000 RPM, 4400 RPM) --- ## 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.fr/products/106292944-2pcs-dc-dc-buck-converter-power-module-3a-adjustable-step](https://www.desertcart.fr/products/106292944-2pcs-dc-dc-buck-converter-power-module-3a-adjustable-step) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-04-23*
