Consists of a source, switch, inductor, capacitor, and flyback diode(this is sometimes replaced by a second transistor acting as a switch for reduced losses).
This circuit topology is used in computer motherboards to convert the 12 V DC power supply to a lower voltage (around 1 V), suitable for the CPU. Modern CPU power requirements can exceed 200 W, [10] can change very rapidly, and have very tight ripple requirements, less than 10 mV. See more A buck converter or step-down converter is a DC-to-DC converter which steps down voltage (while stepping up current) from its input (supply) to its output (load). It is a class of switched-mode power supply. Switching … See more There are two main phenomena impacting the efficiency: conduction losses and switching losses.
