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.


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