*Test ripple and noise by "Parallel cable" method. See detailed operation instructions at Testing of Power
Converter section, application notes.
Note:
1. All specifications measured at T A =25 ℃ , humidity<75%, nominal input voltage and rated output load unless
otherwise specified.
2. See below recommended circuits for more details.
APPLICATION NOTE
Requirement on output load
To ensure this module can operate efficiently and reliably,
During operation, the minimum output load is not less than
10% of the full load, and that his 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.
Recommended circuit
If you want to further decrease the input/output ripple,
an "LC" filtering network may be connected to the input and
output ends of the DC/DC converter, see (Figure 1).
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.
However, the capacitance of the output filter capacitor must
be proper. If the capacitance is too big, a startup problem
might arise. For every channel of output, provided the safe
and reliable operation is ensured, the recommended
capacitance of its filter capacitor sees (Table 1).
TYPICAL CHARACTERISTICS
OUTLINE DIMENSIONS & PIN CONNECTIONS
It not recommended to connect any external capacitor in
the application field with less than 0.5 watt output.
Output Voltage Regulation and Over-voltage Protection
Circuit
The simplest device for output voltage regulation,
over-voltage and over-current protection is a linear voltage
regulator with overheat protection that is connected to the
input or output end in series (Figure 2).
Overload Protection
Under normal operating conditions, the output circuit of
these products has no protection against overload.The
simplest method is to connect a self-recovery fuse in series
at the input end or add a circuit breaker to the circuit.
No parallel connection or plug and play.
