Mixed Distribution
In the real world a combination of parallel and
radial power distribution is often used. Dynamic
and high current loads are connected using a
radial design, while static and low current loads
can be connected in parallel. This combined
approach minimizes the drawbacks of a parallel
design when a purely radial design is not feasible
Redundant Operation
A common requirement in high reliability sys-
tems is to provide redundant power supplies.
The easiest way to do this is to place two con-
verters in parallel, providing fault tolerance but
not load sharing. Oring diodes should be used
to ensure that failure of one converter will not
cause failure of the second. Figure 21 shows
such an arrangement. Upon application of
power, one of the converters will provide a
slightly higher output voltage and will support
the full load demand. The second converter will
see a zero load condition and will “idle”. If the
first converter should fail, the second converter
will support the full load. When designing
redundant converter circuits, Shottky diodes
should be used to minimize the forward voltage
drop. The voltage drop across the Shottky
diodes must also be considered when deter-
mining load voltage requirements.

AV60C-30W Series feature high efficiency and
the 5 V output units have typical efficiency of
87% at full load. With less heat dissipation and
temperature-resistant components such as
ceramic capacitors, these modules exhibit good
behavior during prolonged exposure to high
temperatures. Maintaining the operating case
temperature (Tc) within the specified range help
keep internal-component temperatures within
their specifications which in turn help keep
MTBF from falling below the specified rating.
Proper cooling of the power modules is also
necessary for reliable and consistent operation.
Basic Thermal Management
(Tc) as the method shown in Figure 22 can ver-
ify the proper cooling. Figure 22 shows the
metal surface of the module and the pin loca-
tions. The module should work under 62°C in
natural convection for the reliability of operation
and T
in the final system configuration. The measure-
ment can be made with a surface probe after
