A continuously controlled current increasing charge pump having n series-connected input capacitors coupled to a voltage/current source for developing a constant output voltage of at least ##EQU1## and an output current I.sub.o =nI.sub.in. Regulating circuits are also disclosed to regulate the output voltage. The charge pump consists of plural input switches that switch alternately the positive and negative sides of a like plurality of series-connected capacitors onto at least one output switch and output capacitor. The output switch is synchronized with the input switches and alternates between the negative and the positive output side of each capacitor.
