Our new buck converter also known as “step-down module” is a DC-to-DC power converter that lowers the voltage while decreasing down the current from its input (power supply) to its output (load capacity). 

Step-down modules are used in many instances from power supplies where lower voltages may be needed to achieve low power requirements.



enlightened Adjustable Voltage: Our buck converter can be used with the common input DC voltages of 5V, 9V, 12V, 15V, 18V, 24V and can easily adjust to a DC output voltage between 0.8V to 30V. We highly recommend to always adjust the input voltage at least 2 values higher than the needed output voltage.

enlightened Lower Current Consumption: It's maximum output power consumption is 5A, although it is recommended to use within 3.5A

enlightened Lower Power Consumption: It's maximum output current is 75W, please ensure to install an additional cooling system or heatsink if 50W or more are needed.

enlightened High Efficiency: Its efficiency rate conversion is up to 92%, the efficiency is related to input, output voltage, current, and pressure difference.


What is a buck or step-down converter?

They are like a switched-mode power supply (SMPS) or a “switching power supply” containing at least a diode, a transistor and at least one energy storage element: a capacitor, inductor, or the two in combination. In other words, the buck converter is used to "step-down" an input voltage to some lower level, required by a load. 

For high efficiency, the boost converter must be able to be turned on and off quickly and have low losses. The key feature that drives the boost converter is the tendency of an inductor to resist changes in current by either increasing or decreasing the energy stored in the inductor magnetic field. In a buck converter, the input voltage must always be higher than the output voltage.
