... 1.2.1 DC to DC converter: Two main types of DC to DC converters exist: boost and buck converters. The former enhances the DC voltage presented at its input while the latter steps its down. 1.2.1.1 Boost converter: Boost converters are widely used as a DC to DC step up converter that generates an out ...
Buck converter
A buck converter is a voltage step down and current step up converter.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. Buck converters, on the other hand, can be remarkably efficient (95% or higher for integrated circuits), making them useful for tasks such as converting the main voltage in a computer (12V in a desktop, 12-24V in a laptop) down to the 0.8-1.8V needed by the processor.
