Output Over-Current Protection
AV60A dual output DC/DC converters feature
continuously current limiting as part of their
Overcurrent Protection (OCP) circuits. When
output current exceeds 110 to 140% of rated
current, such as during a short circuit condition,
the output will shutdown immediately, and can
tolerate short circuit conditions indefinitely.
When the overcurrent condition is removed, the
converter will automatically restart.
Output Filters
When the load is sensitive to ripple and noise,
an output filter can be added to minimize the
effects. A simple output filter to reduce output
ripple and noise can be made by connecting a
capacitor across the output as shown in Figure
21. The recommended value for the output
capacitor C1 is 470
F/16V.
Extra care should be taken when long leads or
traces are used to provide power to the load.
Long lead lengths increase the chance for
noise to appear on the lines. Under these con-
ditions C2 can be added across the load as
shown in Figure 22. The recommended compo-
nent for C2 is 470
F/16V capacitor and con-
necting a 0.1
F ceramic capacitor C1 in paral-
lel generally.
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 0.1
F ceramic capacitor across the
load will decouple it. The capacitors should be
connected 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 23. 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 24.
Parallel Power Distribution
Figure 25 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.
