When we want to make a source of energy for our projects, we regularly find certain limitations, which are space, price, heating, etc.
Switching power supplies take advantage of technology to regulate voltage with very high currents (compared to those handled by common regulators.
This source is of the step down type so the input voltage must always be higher than the output voltage.
