Requirement on output load
To ensure this module can operate efficiently
and reliably, During operation, the minimum output load is
not less than 10% of the full load, and that his 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 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).

*Test ripple and noise by "Parallel cable" method. See detailed operation instructions at Testing of Power

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 recommended capacitance
of its filter capacitor sees (Table 1).
OUTLINE DIMENSIONS & PIN CONNECTIONS
It not recommended 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).
Note:
1. All specifications measured at T A =25 ℃ , humidity<75%, nominal input voltage and rated output load unless
otherwise specified.
2. See below recommended circuits for more details.
Overload Protection
Under normal operating conditions, the output
circuit of these products has no protection
against overload. 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.
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.
