APPLICATION NOTE
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
could
not be less than 10% of the full 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 (IF_S(D)
–W25
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 (Table 1).
To get an extremely 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 (Figure 1).

It’s not recommended to connect any external capacitor
in the application field with less than 0.5 watt output.
③
Overload Protection
Under normal operating conditions, the output circuit of these products has no protection
against over-current .The simplest method is to connect a self-recovery fuse in series at the
input end or add a circuit breaker to the circuit.
④
When the environment temperature is higher than 71°C, the product output power
should be less then 60% of the rated power.
⑤
No parallel connection or plug and play.

Note:
1. All specifications measured at TA=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
2. See below recommended circuits for more details.
3. Operation under minimum load will not damage the converter; However, they may not meet all specification listed, and that will reduce the life of product.
