Step-Down Converter Operates from Single Li-Ion Cell
... The circuit of Figure 3 shows the LTC1626 being used for board-level conversion of 5V to 3.3V at up to 0.6A. Although a linear regulator could also perform this function, it would result in an additional 1W of power loss. The high efficiency of the LTC1626 (Figure 4) reduces this loss to only 230mW. ...

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.
