What is a DC/DC converter?

Linear vs. Switching Regulators 2

Switching Regulator

Power is supplied from the input to the output by turning ON a switch (MOSFET) until the desired voltage is reached.
Once the output voltage reaches the predetermined value the switch element is turned OFF and no input power is consumed.
Repeating this operation at high speeds makes it possible to supply voltage efficiently and with less heat generation.
