Paralleling for Lower Output Resistance
Additional flexibility of the LTC660 is shown in Figures 11
and 12. Figure 11 shows two LTC660s connected in
parallel to provide a lower effective output resistance. If,
however, the output resistance is dominated by 1/fC1,
increasing the capacitor size (C1) or increasing the fre-
quency will be of more benefit than the paralleling circuit
shown.
Stacking for Higher Voltage
Figure 12 makes use of “stacking” two LTC660s to provide
even higher voltages. In Figure 12, a negative voltage
doubler or tripler can be achieved depending upon how
Pin 8 of the second LTC660 is connected, as shown
schematically by the switch.
