power conscious single-cell applications. The maximum
output load is 10mA for input voltages greater than or
equal to 1V. A jumper is available to put the circuit into
shutdown mode, which reduces input quiescent current to
5µA (typ) and disconnects V

Demonstration Circuit DC239 is a quadrupler charge pump
DC/DC converter that produces a regulated 3.3V output
from a single alkaline cell input. The circuit requires only
five small external capacitors and no inductors. Low
supply current (40µA typ) and minimal external compo-
nent area make this power supply ideal for space and
