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).

*Supply voltage must be discontinued at the end of short circuit duration.
TYPICAL CHARACTERISTICS
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 recommend to connect any external capacitor in
the application field with less than 0.5 watt output.
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.

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).

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.
