These products apply to:
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 demanded.

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).

When the environment temperature is higher

APPLICATION NOTE
Requirement on output load
Use dual output simultaneously, forbid opening
output pin(0V) to use as single output.
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 (IA_KS
–1W/IA_S-1W series).
Filtering
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).

(Figure 1)
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 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 the EXTERNAL CAPACITOR TABLE (see
Table 1).

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.
