Voltage Doubler/Inverter
Another common application of the TC1219/TC1220 is
shown in Figure 4-6. This circuit performs two functions
in combination. C1 and C2 form the standard inverter
circuit described previously. C3 and C4 plus the two
diodes form the voltage doubler circuit. C1 and C3 are
the pump capacitors and C2 and C4 are the reservoir
capacitors. Because both sub-circuits rely on the same
switches if either output is loaded, both will droop
toward GND. Make sure that the total current drawn
from both the outputs does not total more than 40mA.

Diode Protection for Heavy Loads
When heavy loads require the OUT pin to sink large
currents being delivered by a positive source, diode
protection may be needed. The OUT pin should not be
allowed
to
be
pulled
above
ground.
This
is
accomplished
by
connecting
a
Schottky
diode
(1N5817) as shown in Figure 4-7.
4.11
Layout Considerations
As with any switching power supply circuit good layout
practice is recommended. Mount components as close
together as possible to minimize stray inductance and
capacitance. Noise leakage into other circuitry can be
minimized with the use of a large ground plane.
