6-25V Dual USB Step Down Regulator


Availability: In Stock

Need a convenient USB charge port? This buck regulator is designed to take up to 25V in, and provide 5V out by way of two standard USB A ports.


SKU: REG-027 Category: Tag:


This buck regulator is designed to step down an input voltage of 25V to an output voltage of 5V. The buck regulator’s primary function is to lower the voltage while increasing the current from its input to its output in a process known as step-down conversion. The regulator can provide up to 3A output and features up to 92% efficiency.

The power output is made accessible through two USB Type-A ports, ideal for charging or powering various USB-enabled devices. Each USB port has the required resistor for Apple devices to recognize it as a power source. To power the board there are two connection points: a large set of screw terminals or a 2.1 x 5.5mm DC Barrel Jack. The module measures 49.8 x 36.2 x 15mm and has three M2 compatible mounting holes.

    dear bc-robotics,
    I was wondering weather this regulator can handle 14.6 amps.
    I am planning on adding Bluetooth RGB leds to my 3d printer, and need to power my Arduino off of the printer’s 24V 350W 14.6A power supply. I am wondering if this could work for that?

      Hi Ethan,

      The 14.6 amps is not the part to be (as) concerned about, this is the same as worrying about how much gas is in the gas tank. You really need to worry about the voltage (or the type of gas) – and 24V is just about the maximum input for this power supply. You will need to be careful with the load on this regulator as it will overheat.

      Best to have a look through this tutorial: Electricity Basics

    So I could technically use this for 24v, but with a heat sink or fan or something?
