APPLICATION NOTE 1199
Voltage-Inverter IC Forms High-Efficiency Rail Splitter
A switched-capacitor voltage inverter configured as a "rail splitter" (IC1 in Figure 1) provides a bipolar (dual-
rail) local power supply that is useful in single-rail systems featuring one or more dual-rail ICs. Moreover, the
tiny SOT-23 package and associated components require very little board area.




Figure 1. This compact and efficient charge-pump circuit implements a local dual-rail supply for single-rail
systems.

After power is applied, the flying capacitor (C2) connects alternately across the storage capacitors C3/C4 and C5/
C……
