APPLICATION NOTES
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, 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 (VIAS1-SIP series).
2.
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 proper. If the capacitance is too big, a
startup problem might arise. For every channel of output, providing the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor refer to 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).
3.
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.
