Buck is a term used to describe a type of voltage regulator that reduces, or bucks, the voltage of an input signal to a lower voltage level.
It does this by converting the excess voltage into heat, which is then dissipated.
Buck regulators are widely used in power supply design, as they are simple, efficient, and cost-effective.
They are commonly used to regulate the voltage for microprocessors, FPGAs, and other digital circuits.
Buck regulators work by switching the input voltage on and off rapidly, creating a series of pulses that are smoothed by an output filter to produce a steady voltage at the output.
The switching frequency can be adjusted to control the output voltage and the efficiency of the regulator.
