MAX20003CATPC/V+T Datasheet/PDFDC DC Switching Regulators
A DC-DC switching regulator is an electronic power conversion device that is used to provide regulated output voltages from a DC input supply. It is capable of providing the same voltage as that of the input, but at an efficiency level much higher than other forms of regulation. The DC-DC switching regulator can also be used as an electromechanical device to drive sensitive loads and achieve higher efficiency levels.
The DC-DC switching regulator can be used to provide regulated output voltages with a large dynamic range and low noise levels. It works by using the principle of an external inductor and capacitor combination to transform the input voltage into a higher regulated voltage. This is done by switching an electronic switching element between the input and output at predetermined intervals. These intervals are determined by an electronic circuit which monitors the input voltage and regulates the output voltage accordingly.
