Decoupling
Noise on the power distribution system is not
always created by the converter. High speed
analog or digital loads with dynamic power
demands can cause noise to cross the power
inductor back onto the input lines. Noise can be
reduced by decoupling the load. In most cases,
connecting a 10 F tantalum capacitor in paral-
lel with a 1 F ceramic capacitor across the load
will decouple it. The capacitors should be con-
nected as close to the load as possible.
Ground Loops
Ground loops occur when different circuits are
given multiple paths to common or earth
ground, as shown in Figure 16. Multiple ground
points can slightly different potential and cause
current flow through the circuit from one point to
another. This can result in additional noise in all
the circuits. To eliminate the problem, circuits
should be designed with a single ground con-
nection as shown in Figure 17.

Parallel Power Distribution
Figure 18. shows a typical parallel power distri-
bution design. Such designs, sometimes called
daisy chains, can be used for very low output
currents, but are not normally recommended.
The voltage across loads far from the source
can vary greatly depending on the IR drops
along the leads and changes in the loads clos-
er to the source. Dynamic load conditions
increase the potential problems.
Radial Power Distribution
Radial power distribution is the preferred
method of providing power to the load. Figure
19. shows how individual loads are connected
directly to the power source. This arrangement
requires additional power leads, but it avoids
the voltage variation problems associated with
the parallel power distribution technique.
