Application Notes:
- Filtering
In some circuits which are sensitive to noise and
ripple, a filtering capacitor may be added to the
DC/DC output end and input end to reduce the noise
and ripple. However, the capacitance of the output
filter capacitor must be appropriate. If the
capacitance is too big, a startup problem might arise.
For every channel of output, providing that safe and
reliable operation is ensured, the greatest
capacitance of its filter capacitor is shown in the
External Capacitor Table. To get an extreme low
ripple, an “LC” filtering network may be connected to
the input and output ends of the DC/DC converter,
which may produce a more significant filtering effect.
It should also be noted that the inductance and the
frequency of the “LC” filtering network should be
staggered with the DC/DC frequency to avoid mutual
interference (see figure 1).
- Requirement on Output Load
To ensure this module can operate efficiently and
reliably, a minimum load is specified for this kind of
DC/DC converter in addition to a maximum load
(namely full load). During operation, make sure the
specified range of input voltage is not exceeded, the
minimum output load is not less than 10% of the
full load, and that this product should never be
operated under no load! If the actual output power is
very small, please connect a resistor with proper
resistance at the output end in parallel to increase
the load, or use our company’s products with a lower
rated output power.
- Overload protection
Under normal operating conditions, the output circuit
of these products has no protection against
over-current and short-circuits. The simplest method
is to connect a self-recovery fuse in series at the
input end or add a circuit breaker to the circuit.
