It supports input voltages from 6V to 32V and outputs adjustable voltages from 1.25V to 32V at up to 5A, making it ideal for precise power management in electronics, battery charging, and LED driving applications. The included USB port and protective casing enhance usability and durability for professional-grade projects. ## Description Parameters: Input voltage: 6~32V Output voltage: 1.25~32V (Input must be 1.5 higher than output.) Output current: Max.5V, adjustable, recommend the use of within 4.5A. (Over 2A or 35W, please enhance heat dissipation.Constant current needs above 2V output voltage, then can be adjusted. Only in the status of constant current can current adjustment work.) Output Power: Max.75W (recommend the use of within 50W, please reduce power if the dropout voltage is large) Operating temperature: -20 ~+70℃ Operating frequency: 180KHz Conversion efficiency: up to 96% Short circuit protection: Yes Input reverse polarity protection: None Over-temperature protection: Yes (Automatically shut off the output when over-temperature.) Connection: terminals or solder terminals; VIN is input; VOUT is output Module dimension: 65.6 x 40 x 25mm Voltage-calibration Method: In the case of power off, press and hold the "SET" key and power on, then enter into voltage calibration mode, and LCD screen starts to flash, release the "SET" key; press "SET" and "ENT" key to increase or reduce the voltage to the right input voltage. It will automatically saves after 2s, then power off and the calibration is complete. Current-calibration Method: Suitable for no-load with current display or slightly large current. In the case of power off, press and hold "ENT" and power on, then enter into current calibration mode and LCD screen starts to flash, release the "ENT" key; press "SET" and "ENT" key to increase or reduce the voltage to the right value. It will automatically saves after 2s, then power off and the calibration is complete. Package Includes: 2 x DC-DC Adjustable Step-down Power Supply Module with Shell 8 x Copper Cylinder Screws M3*6 8 x Double-pass Screws M3*12 16 x Roundhead Screws M3*6 Review: Works Great!!! - Works Great!!! Review: I had tried to design my own buck converter, taking the voltage from 14V to 5V and found that it was very difficult to do this reliably and with minimal noise on the output. I was looking to power an RF circuit. This Drok DC Buck Converter is amazing! It can handle the job with ease, and the output is very clean allowing my RF circuit to function properly. This converter has a place on the plastic housing for a fan, but so far heat has never been an issue while running at 1 amp or less. There are a few things to watch out for! First, make sure you have the converter set to the correct voltage before connecting power to your project. Secondly, the USB port can operate at voltage that are higher than normal USB spec. If you have the converter set to output 10V, the USB will also be 10V, instead of the normal 5V. This could damage equipment if you aren't aware. Next, the USB port does no remain enabled during a power off/on sequence. The converter WILL remember the voltage setting, but the port disables until you manually re-enable it. Idle current consumption is around 15-20ma at 14VDC, even with the display backlight turned off. Connections are all made using USB or screw terminals. Overall a top performer and good value for the price! ## Features - Come with protective shell, Large LCD screen, blue background and white digit, can be clearly seen in any angle, displaying voltage and current simultaneously. - A constant voltage and current module, Input voltage could be 6-32V; Output voltage could be 1.25~32V; input side must be 1.5 higher than output side; max output Power is 75W. - Made of imported MP2304 chip, high conversion efficiency of 96%, when current is higher than 3A or 35W, please enhance heat dissipation. - With voltage-calibration and current-calibration, designed with USB interface, it brings you many conveniences in most occasions. - Wide applications：used as an ordinary step-down modules with over-current protection capabilities, as a battery charger, as a constant current LED driver module. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CXT83GV6 | | Best Sellers Rank | #15,442 in Electronics ( See Top 100 in Electronics ) #291 in International Power Adapters | | Item model number | F-MP2304 | | Item weight | 0.14 Kilograms | | Manufacturer | DROK | | Package Dimensions | 14 x 9.7 x 5.6 cm; 141 g | ## Product Details - **Brand:** DROK - **Current rating:** 5 Amps - **Mounting type:** Portable - **Power source:** Corded Electric - **Specification met:** CE, RoHS, UL ## Images ![DC Adjustable Buck Converter 2pcs, 24v to 12v Step Down Converter Voltage Regulator 6V-32V to 1.5-32V 5V 5A LCD Power Supply Volt Reducer Step Down Transformer with USB Port and Protective Case - Image 1](https://m.media-amazon.com/images/I/71Sz58OZ1UL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐ Works Great!!! *by M***R on 6 August 2025* Works Great!!! ### ⭐⭐⭐⭐⭐ Review *by E***U on 27 January 2026* I had tried to design my own buck converter, taking the voltage from 14V to 5V and found that it was very difficult to do this reliably and with minimal noise on the output.
