Since both V
+
and V
–
are separately generated
from V
CC
, in a no–load condition V
+
and V
–
will
be symmetrical. Older charge pump approaches
that generate V
–
from V
+
will show a decrease in
the magnitude of V
–
compared to V
+
due to the
inherent inefficiencies in the design.

The clock rate for the charge pump typically
operates at 250kHz. The external capacitors can
be as low as 0.1
μ
F with a 16V breakdown
voltage rating.
