    Tips: Difference between DC-DC buck converter and boost converter

    DC-DC buck converters and boost converters are two common types of power converters, and the main difference between them is the relationship of their output voltage relative to the input voltage.

    • Buck converter: A buck converter reduces the input voltage below the output voltage. This means the output voltage is less than the input voltage and is often used to convert high voltage to a lower voltage, such as converting 12V from a car battery to 5V for use in electronic devices.
    • Boost converter: A boost converter increases the input voltage above the output voltage. This means the output voltage is higher than the input voltage and is often used to convert a low voltage to a higher voltage, such as boosting a battery's 3.7V to 5V for USB charging.

    Highly recommend this DC-DC buck converter
    I used this DC-DC buck converter to step down my 48 volt solar system to 24 volts to run a few 24 volt appliances, easy to install and has done a great job. Highly recommend this product and this company.

    48V to 24V converter is working great
    Made a portable power supply to step down my 48V tool batteries to 24V, this converter is working great. This is my second purchase. Easy installation. Recommend to install in a dry location even though it looks well sealed and make sure it can cool properly.
