A buck regulator, also known as a step-down regulator, is a type of voltage regulator widely employed in electronic devices and power supply circuits to efficiently reduce an input voltage to a lower, desired output voltage.
The primary function of a buck regulator is to step down the voltage from a higher level, typically from a power source such as a battery or external power supply, to a level suitable for powering sensitive electronic components.
This process is crucial in maintaining stable and reliable voltage levels, which is essential for the proper operation of electronic devices.
