Glossary Definition for Charge-Pump

Glossary Term: Charge-Pump 

Definition

A power supply which uses capacitors to store and transfer energy to the output, often stepping the voltage up or down. Charge is transferred from one capacitor to another under control of regulator and switching circuitry.

Maxim offers both regulated and non-regulated charge pumps, as well as ICs with on-board charge pumps to boost internal voltages.

See application note 2031, "DC-DC Converter Tutorial" and application note 660, "Regulator topologies for battery-powered systems."
