APPLICATIONS

The D-XNS-2W series are specially designed for

applications where a group of polar power supplies are

isolated from the input power supply in a distributed

power supply system on a circuit board.

D-XNS-2W Series

Filtering

To get the input/output 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).

Short circuit protection*

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 (Table 1).

It's not recommend 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).

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!

RoHS COMPLIANT INFORMATION

This series is compatible with RoHS soldering systems with a peak wave solder temperature

of 300°C for 10 seconds.

The pin termination finish on the SIP package type is Tin Plate, Hot Dipped over Matte Tin

with Nickel Preplate. The DIP types are Matte Tin over Nickel Preplate. Both types in this

series are backward compatible with Sn/Pb soldering systems.
