PARALLELING DEVICES
Any number of MAX660s can be paralleled to reduce the output resistance. Each device must have its own pumping capacitor
C
CASCADING DEVICES
Cascading the is an easy way to produce a greater negative voltage (as shown in Figure 6 ). If n is the integer representing the
number of devices cascaded, the unloaded output voltage V
sum of each individual device:
