The switch’s duty cycle sets the amount of charge transferred to the load. This is controlled by a feedback mechanism similar to that of a linear regulator. Switching regulators are efficient because the series element is either fully conducting or switch https://www.futureelectronics.com/c/semiconductors/analog--regulators-reference--switching-regulators/products
