Efficient Positive Voltage
Multiplication/Conversion
Since the switches that allow the charge pumping
operation are bidirectional, the charge transfer can be
performed backwards as easily as forwards.
(or +5V to +10V, etc.). The only problem here is that the
internal clock and switch-drive section will not operate
until some positive voltage has been generated. An ini-
tial inefficient pump, as shown in Figure 5-7 , could be
used to start this circuit up, after which it will bypass the
other (D 1 and D 2 in Figure 5-7 would never turn on), or
can be used to “force” the internal regulator on.
