APPLICATIONS
COMMON SPECIFICATIONS
The MA_XD-1W & MA_XD-2W Series are specially
designed for applications where group of polar
power supplies are isolated from the input power
supply in distributed power supply system on
circuit board.

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 out put
filter capacitor must be proper .If the capacitance is too big, a startup
problem might arise. For every channel of out put , provided the safe
and reliable operation is ensured, the greatest capacitance of its filter
capacitor sees (Table 1).

*Supply voltage must be discontinued at the end of short circuit duration.
TYPICAL CHARACTERISTICS
It’s not recommended to connect any external capacitor in the
application field with less than 0.5 watt output.
TYPICAL CHARACTERISTICS
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).
When the environment temperature is higher than 71°C, the
product output power should be less then 60% of the rated power.
No parallel connection or plug and play.
APPLICATION NOTE
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 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, or use our company’s products with a lower rated output power.
