## Description

Features: - DC to DC buck converter module - Thickened circuit boards - Advanced solid-state capacitor - Short circuit and over-temperature protection - 100% tested, sealed in anti-static packaging Kindly Note: 1. Input voltage must be 1.5 V higher than the output voltage, no boost 2. Do not reverse the input and output interface 3. Keep output under 2.5A (or 10W) and use a heat sink when for a long time working4. The factory settings stay a high voltage, you may need to contrarotate the screw on blue potentiometer about 7-15 circles before the output voltage changes  Specifications: - Type: DC-DC buck converter - Input voltage: DC 3.2V - 35V - Output Voltage: DC 1.25V - 30V (adjustable) - Output Current: 3A (max.) - Output Power: 15W (max.) - Conversion Efficiency: 92% (max.) - Switching Frequency : 65KHz - Rectification: non-synchronous rectification - Module property: non-isolated buck module - Operating Temperature: -45℃ to +85℃ - Load Regulation: ± 0.5% - Voltage Regulation: ± 2.5% - Size(L x W x H): 45*23*14mm / 1.77*0.91*0.55inch - Weight: 14g Package List: 8x DC to DC Buck Converter Module

## Features

- 【High Precision】The buck converter consists of 36u thickened circuit boards, high-Q inductance with output LED indicator, and superior solid-state capacitors that can effectively filter out high frequency noise. Suitable for various electronic projects.
- 【Input Voltage】DC 3.2V to 35V (input voltage must be 1.5V higher than the output voltage, no boost).
- 【Output Voltage】DC 1.25V to 30V voltage is continuously adjustable, maximum output current is 3A.
- 【Mini Size】45 * 23 * 14 mm (with potentiometer). 8pcs included.
- 【Easy to DIY】Connect to power source, using a mini screwdriver to increase or decrease output voltage by adjusting the screw on the blue potentiometer and monitor voltage with multimeter to get the needed voltage, clockwise to increase voltage and counterclockwise to decrease voltage. (Factory default stays a high voltage, you need to contrarotate about 7-15 circles before the voltage starts ramping down, 1 circle means +/- 1V)

## Customer Reviews

### ⭐⭐⭐⭐⭐ perfect for a diy projects
*by A***X on 8 July 2020*

This step down module helped me with my old rechargable batteries and use them in to something new. It is a great value for money an it is usefull for a many purposes. Small and eficient with a wide range of voltage. I am still new to electronics and it is very easy to use this little board. It comes in a box and individualy packed.

### ⭐⭐⭐⭐ Does the job
*by G***R on 9 April 2020*

I wanted a low cost, small, device to power some LEDs, these seemed to meet the requirements but the first example didn't allow the output to be adjusted, a second one proved to work as expected and the required voltage was set although a lot of turns of the potentiometer were required to achieve it.The rating reflects the absence of any documentation in the package meaning that there is a degree of trial and error in using these regulators.Having read the details on the product page I have determined that these regulators are extremely robust and very easy to set-up once you know what to do. As delivered the output voltage will always reflect the input voltage so, unless you have a 40V supply, it will be necessary to rotate the potentiometer several turns until the output voltage drops below the input.I inadvertently connected one the wrong way round but reversing the input polarity resulted in it working perfectly. As the original requirement as for one device I have a further seven for other projects.

### ⭐⭐⭐⭐⭐ Excellent value
*by B***P on 24 September 2019*

I bought these because our Carson 14ch RC receiver outputs 5.9v but several electronic switches need 5v and some LEDs need 3.3v. They work perfectly. Be prepared to turn the adjustment screw a lot before hitting the voltage range you need then just fine adjustment required. They feel well made and testing with digital equipment shows just a tiny inaccuracy which is well within acceptable limits. Overall - excellent value and recommended.
