Mini DC-DC Boost Step Up Converter with an output voltage greater than the source voltage. The output current is lower than the source current. This is a high voltage step-up power supply module, which is commonly used in electronics experiments and demonstrations. The high-voltage module uses the principle of the Tesla coil. The voltage boost converter module provides 3.7V DC stable voltage output at various input ranges between 3.7V to 12V. This small, tiny circuit boosts the voltage level and provides the amplified stabilized 5V/ 8V/ 9V 12V output. For the different input ranges, it consumes a different amount of current to produce a balanced output.
