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.
Recommended testing and application 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).
KHz
*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 TA=25°C, humidity<75%, nominal input voltage and rated output load
unless otherwise specified.
2. See below recommended circuits for more details.

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 greatest
capacitance of its filter capacitor sees (Table 1).

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
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.
No parallel connection or plug and play.
