Figure 26. TPS60400 as a High-Efficiency Rail Splitter
A switched-capacitor voltage inverter can be configured as a high efficiency rail-splitter. This circuit provides a
bipolar power supply that is useful in battery powered systems to supply dual-rail ICs, like operational amplifiers.
Moreover, the SOT23-5 package and associated components require very little board space.
After power is applied, the flying capacitor (C
(fly)
) connects alternately across the output capacitors C
3
and C
O
.
This equalizes the voltage on those capacitors and draws current from V
I
to V
O
as required to maintain the
output at 1/2 V
I
.
The maximum input voltage between V
I
and GND in the schematic (or between IN and OUT at the device itself)
must not exceed 6.5 V.
