Other Applications
Paralleling Devices
Any number of LM2765s can be paralleled to reduce the out-
put resistance. Each device must have its own pumping ca-
pacitor C
1, while only one output capacitor Cout is needed as
shown in Figure 3. The composite output resistance is:
Cascading Devices
Cascading the LM2765s is an easy way to produce a greater
voltage (A two-stage cascade circuit is shown in Figure 4).
The effective output resistance is equal to the weighted sum
of each individual device:
R
out = 1.5Rout_1 +Rout_2
Note that increasing the number of cascading stages is prac-
itically limited since it significantly reduces the efficiency, in-
creases the output resistance and output voltage ripple.
