Paralleling Devices
Paralleling multiple TCM680s reduces the output resis-
tance of both the positive and negative converters. The
effective output resistance is the output resistance of a
single device divided by the number of devices. As illus-
trated in Figure 7, each requires separate pump capacitors
C1 and C2, but all can share a single set of reservoir
capacitors.
±5V Regulated Supplies From A Single
3V Battery
Figure 8 shows a complete
±5V power supply using one
3V battery. The TCM680 provides +6V at V
+
OUT, which is
regulated to +5V by the TC55, and –5V by the negative LDO.
The input to the TCM680 can vary from 3V to 6V without
affecting regulation appreciably. With higher input voltage,
more current can be drawn from the outputs of the TCM680.
With 5V at VIN, 10mA can be drawn from both regulated
outputs simultaneously. Assuming 150
Ω source resistance
for both converters, with (I
+
L + IL) = 20mA, the positive charge
pump will droop 3V, providing +7V for the negative charge
pump.
