About Charge Pumps
Charge pumps are circuits that generate higher voltages from low-voltage inputs by using capacitors as storage elements. Charge pumps are used in notebook computers and mobile phones. There are many types of charge pumps. Examples include charge pump phase-locked loops (CPPL), converter chips, IC converters, inductorless converters, and inductorless regulators. A charge pump phase-locked loop (CPPLL) can provide zero phase-error and an extended frequency range of operations. Converter chips can be used for both analog/digital (A/D) and digital/analog (D/A) conversions. IC converters are used in battery-operated, handheld devices. An inductorless converter can be used as a DC-DC inverter, splitter, or doubler. An inductorless regulator provides output regulation for portable applications. Specialized and proprietary charge pumps may also be available.
