DC-DC Converter
<What is a DC-DC Converter?>

As its name implies, a DC-DC converter converts one DC voltage to another.

The operating voltage of different electronic devices such as ICs can vary over a wide range, making it necessary to provide a voltage for each device.

A Buck Converter outputs a lower voltage than the original voltage, while a Boost Converter supplies a higher voltage.  

Linear or Switching Regulators

DC-DC converters are also referred to as linear or switching regulators, depending on the method used for conversion.
