Features

  • Product parameters: input voltage is 4.0V - 40V, output voltage is 1.25V - 37V, output current is 2A (normal and stable) and 3A max, conversion efficiency 92% (highest), output ripple under 30mV, switching frequency 150KHz, operating temperature is -45 to 85 degree Celsius
  • Simple to operate: the voltmeter can be turned off, and the switch can be turned off by pressing and holding the switch for more than 1 second and less than 4 seconds, once the voltmeter is turned off, simply press the switch to turn on the voltmeter
  • Easy to use: with terminal block, no soldering iron is also convenient to use, and retain the wire bond point (the input voltage must be higher than the voltage to be output by 1v or more)
  • Output current: the maximum output current can be as high as 3A, the recommended working current is about 2A, more than 2A plus heat sink
  • Nice design: with 150KHz internal oscillation frequency, features low power consumption and high efficiency; When the output voltage cannot be adjusted and is always equal to the input voltage, please turn the potentiometer counterclockwise for more than 10 turns, and then use the module to adjust the voltage normally; This is because when the module leaves the factory, the default output voltage is about 20V

    Best buck converters – Buyer’s Guide 2021

    There are some things you should consider when buying a buck converters. We spent 22 hours researching the most important things you should consider when buying a buck converters. So should we start with the list of things you should consider?

    1. Budget and price matching

    Make a list of the things you want in your buck converters and the price you are willing to pay for it. So try to look for a product in that price range and choose the one that appeals to you the most. One tip we would like to give you is: don’t settle for a cheaper product if it doesn’t even have a function you need.

    Most buck converterss fall within the price range of $ 14.99 to $ 10.98. Therefore, if budget is not a problem and you want the best product for your needs, we advise you to choose the 4 Pieces Adjustable LM2596S DC-DC Buck Converter Reduced Voltage Regulator Power Module 36V 24V 12V to 5V 2A Voltage Stabilizer with Digital Voltmeter Display.

    If you want something medium range, choose Dorhea 7PCS LM2596 DC to DC Buck Converter Voltage Regulator 3.0-40V to 1.5-35V Buck Converter DIY Adjustable Power Supply Step Down Module.

    2. Does it have all the features you need?

    Most importantly, the buck converters you are purchasing should have all the features you are looking for. In case you don’t even have one, don’t buy! We are saying this because you will not be able to use it for that purpose. If you are a person without budget problems, I would suggest you to choose the best model which is Valefod 6 Pack LM2596 DC to DC High Efficiency Voltage Regulator 3.0-40V to 1.5-35V Buck Converter DIY Power Supply Step-Down Module

    3. The brand

    Buying the buck converters from a reputable brand can actually make sense. Not only will it be better than others in terms of “build quality”, but it will also have some extra features, better customer support. Famous brands have multiple service centers across the country, so if you have any problems you can simply take your buck converters to one of their service centers.

    4. Warranty Matters!

    When you buy a buck converters from a well-known brand, you will get a guarantee. Low-cost products also come with warranties, but the claim process could be tougher. That’s why I always suggest you buy the product from a reputed brand and the one that comes under warranty. It will save you from repair costs in the future. On average, around 21% of people end up paying 40% of the product price for the service! You can save on service costs if the product is under warranty!
