• Manufacturer Part Number: FB1205N-1W
• Description: SINGLE OUTPUT DC-DC CONVERTER
• Manufacturer: MORNSUN [MORNSUN Science& Technology Ltd.]

*Test ripple and noise by “parallel cable” method. See detailed operation instructions at Testing of
Power Converter section, application notes.
Requirement on output load
output load is not less than 10% of the full load, and that this 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.

Recommended testing and application circuit
input/output ripple, an “LC” filtering network may
be connected to the input and output ends of the
DC/DC converter, see (Figure 1).
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).

regulation,
protection is a linear voltage regulator with
overheat protection that is connected to the input
or output end in series (Figure 2).
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.
It should also be noted that the inductance and
