A Linear voltage regulator is a common easy to use electronic components which requires an input supply, two capacitors (one for input and other for output). are quite easy to use but they are inefficient. They dissipate a large amount of heat thus raising the temperature as well. This, in turn, restricts us to use large-sized heat sinks with them.
A buck converter is an efficient device which is available in different sizes. Usually, the buck converter is also known as voltage step down converter. Many models involve a potentiometer which can be used to achieve the desired amount of voltage.
In this video, you’ll learn the difference between buck converters and linear regulators. The working of both components is illustrated. Linear voltage regulators are inefficient they dissipated a lot of heat and also raise the temperature. So you need to use a heat sink with it. On the other hand buck converter is a voltage step-down converter which is an efficient device which provides a constant voltage output and whose output is adjusted by the potentiometer.
