Typical graphs of the total power consumption of the
PCF2119x using the internal charge pump are illustrated
in Figs.34 to 36.
The graphs were obtained under the following conditions:

For each multiplication factor there is a separate line. The
line ends where it is not possible to get a higher voltage
under its conditions (a higher multiplication factor is
needed to get higher voltages).
Connecting different displays may result in different
current consumption. This affects the efficiency and the
optimum multiplication factor to be used to generate a
certain output voltage.
