DC DC voltage regulators convert a fixed DC voltage into a variable DC voltage, usually to effectively output a fixed voltage. 
The advantages of DC DC voltage regulators are high efficiency, the ability to output large currents, and low quiescent current.
There are different types of DC DC voltage regulators that support different design circuits such as boost, buck, and lift outputs.
DC DC voltage regulators are generally composed of control chipinductor coildiodetransistorcapacitor, some more need MOSFET, especially Boost circuit.
