The most basic topology for switching regulators and one that always steps the voltage down is the
A) buck regulator.
B) boost regulator.
C) shunt regulator.
D) series regulator.

Question

Quizplus · Accepted Answer

A buck regulator is the most basic topology for switching regulators and always steps the voltage down. It operates by switching a series transistor on and off, which creates a varying voltage across an inductor. This varying voltage is then smoothed out by a capacitor and output as a lower voltage than the input. The buck regulator is commonly used to regulate the voltage of battery-powered devices, such as cell phones and laptops.
