1) Where the voltage of the input power supply
is fixed (voltage variation ≤ ±5%);

2) Where isolation is necessary between input
and output (isolation voltage ≤1000VDC);
3) Where the regulation of the output voltage and
the output ripple noise are not demanding.

APPLICATION NOTE
1) Requirement on output load
(Figure 2)
To ensure this module can operate efficiently and reliably, During operation, 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

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 greatest capacitance of its filter capacitor sees (Table 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) Input Over-voltage Protection Circuit
The simplest device for input over-voltage protection is a linear voltage regulator with
overheat protection that is connected to the input end in series (Figure 2).
5) No parallel connection or plug and play

Note:
1. 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.
2. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
3. Only typical models listed, other models may be different, please contact our technical person for more details.
4. In this datasheet, all the test methods of indications are based on corporate standards.
