There are two possibilities for the output capacitors in a boost regulator for a modern design. This bank of capacitors is either comprised of nothing but multilayer ceramics, or MLCCs, or it’s a mixture of MLCCs and other technologies that provide more capacitance, but have other drawbacks. I refer to these as buck capacitors.
To successfully increase capacitor voltage beyond the driving voltage, we need to “pump” charge into the capacitor and prevent charge from flowing back into the source. The boost converter’s diode, which functions as a one-way valve for current, provides both of these actions:
Efficient regulation ensures that the boost converter can maintain a constant output voltage despite variations or changes in the input voltage which contributes performance and its reliability. Hence this working mode makes the boost converter efficiency in stepping up voltage levels.
Conversely, a boost converter takes a DC input voltage and produces a DC output voltage that is higher in value than the input, but of the same polarity. When the switch is turned on, the input voltage is forced across the inductor, causing the current to ramp up.
