What Is a Buck Converter?
A buck converter is a type of DC-DC converter commonly used in power supplies.
Its primary function is to reduce the voltage from the input to the output while increasing the current. This is achieved by using a coupled inductor between the input and output and controlling the input current with a switching device.
Key features of a buck converter include its compact and lightweight design, consisting of only a switching device and a coupled inductor. This simplicity results in highly efficient operation and minimal power losses. Additionally, it can provide a stable output voltage even when the input voltage varies over a wide range.
