A typical portable electronic device, such as a mobile phone or all MP3 player, comprises a variety of chips many of which need different power-supply voltages. For instance. USB OTG (on the go) needs it 5V source, analog sections and interfaces require 3.3V, and RF chips need
2.5 and 1.8V sources. To compound the issue, current requirements for the chips vary, as does the quality of the power. Design engineers usually resort to a plethora of power-supply regulators with varying voltage, current, and noise specifications to meet the power demand. which results in a proliferation of power-regulator chips, consumption of precious board space, and increased bill-of-material costs. …
