A buck converter is a step-down DC to DC converter. Its design is similar to the step-up boost converter, and like the boost converter it is a switched-mode power supply that uses two switches (a transistor and a diode), an inductor and a capacitor.
The simplest way to reduce the voltage of a DC supply is to use a linear regulator (such as a 7805), but linear regulators waste energy as they operate by dissipating excess power as heat.

The switching regulator is increasing in popularity because it offers the advantages of higher power conversion efficiency and increased design flexibility (multiple output voltages of different polarities can be generated from a single input voltage). This paper will detail the operating principles of the four most commonly used switching converter types: Buck: used the reduce a DC voltage to a lower DC voltage. Boost: provides an output voltage that is higher than the input. Buck-Boost (invert): an output voltage is generated opposite in polarity to the input....
The ability of certain materials to convert sunlight to electricity was ﬁrst discovered by Becquerel in 1839, when he discovered the photogalvanic effect. A number of other signiﬁcant discoveries ultimately paved the way for the fabrication of the ﬁrst solar cell in 1954 by Chapin, Fuller, and Pearson . This cell had a conversion efﬁciency of 6%. Within 4 years, solar cells were used on the Vanguard I orbiting satellite. The high cost of boosting a payload into space readily justiﬁed the use of these cells, even though they were quite expensive.
