It is a kind of switching-method DC-DC converters that switches the input power and controls the output power by turning on and off the semiconductor switching devices such as power MOSFET. Regulator is a kind of circuit that functions to regulate the output voltage and current to become constant. DC-DC converter is a DC voltage converter that outputs different DC voltages for a certain DC input voltage.
