What is a DC/DC converter?

Linear vs. Switching Regulators 1

A DC/DC converter that stabilizes the voltage is often referred to as a voltage regulator.
Two types of regulators exist, classified by conversion method: linear and switching.

Linear Regulator

As its name suggests, a linear regulator is one where the relationship between the input and output is linear.
It is also sometimes called a series regulator because the control elements are arranged in series between the input and output.

Advantages Disadvantages
  • Simple circuit configuration
  • Few external parts
  • Low noise
  • Relatively poor efficiency
  • Considerable heat generation
  • Only step-down (buck) operation
