charge pump
(1) A dc-to-dc converter in which a capacitor is charged from a voltage source and then electrically reconnected in series with that source to make available a voltage greater than that of the source.
NOTE This type of dc-to-dc converter is sometimes called a voltage doubler or, when several stages are cascaded, a voltage multiplier.
(2) A dc-to-dc converter in which a capacitor is charged from a voltage source and then electrically reconnected to make available a voltage whose polarity is opposite to that of the source.
