Our new boost converter also known as “step-up converter” is a DC-to-DC power converter that amplifies the voltage while decreasing down the current from its input (power supply) to its output (load capacity). We have also gone a step further and included a digital voltmeter to monitor and adjust potentiometer.

Boost converters or step-up converters are used in many instances from small power supplies where higher voltages may be needed to much higher power requirements.



enlightened Low & Adjustable Voltage: Its DC input voltage is 3-34V and it adjusts to a DC output voltage of 4-35V, please remember that this is a boost module, therefore,  the output voltage must be greater than the input voltage. 

enlightened Lower Current Consumption: Its maximum output current is 2.5A, please ensure that the peak output current does not exceed 2.5A. It also supports a maximum input current of 3A, please ensure that it does not exceed 3A.

enlightened Additional Voltmeter: The voltmeter error is + / - 0.1V, the range is 0 to 40V, to ensure the voltage meter accuracy, please make sure that the input voltage is more than 3V. For a voltmeter to measure a device’s voltage, it must be connected in parallel to that device. This is due because objects in parallel have the same potential difference.

enlightened Touch Keys: Easy to use touch keys to measure input and output voltage, press the touch button lightly to turn on the LED display and long press for 3 seconds to turn off the power display.


What is a boost or step-up 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 boost converter is used to "step-up" an input voltage to some higher level, required by a load. This unique capability is achieved by storing energy in an inductor and releasing it to the load at a higher voltage.

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 boost converter, the output voltage must always be higher than the input voltage.
