CASCADING DEVICES
Cascading the LM2660s (or LM2661s) is an easy way to produce a greater negative voltage (as shown in Figure 5). If n is the
integer representing the number of devices cascaded, the unloaded output voltage V
out
is (nV
in
). The effective output resistance
is equal to the weighted sum of each individual device:
A three-stage cascade circuit shown in Figure 6 generates 3V
in
, from V
in
.
Cascading is also possible when devices are operating in doubling mode. In Figure 7 two devices are cascaded to generate 3V
in
.
An example of using the circuit in Figure 6 or Figure 7 is generating +15V or 15V from a +5V input.
Note that, the number of n is practically limited since the increasing of n significantly reduces the efficiency and increases the out-
put resistance and output voltage ripple.
