APPLICATIONS
The A_XM-1W&B_XLM-1W 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.
These products apply to:
1) Where the voltage of the input power supply
is fixed (voltage variation ≤ ±10%);
2) Where isolation is necessary between input
and output (isolation voltage ≤1000VDC);
3) Where the regulation of the output voltage
and the output ripple noise are not demanding.
Such as: purely digital circuits, ordinary low
frequency analog circuits, and IGBT power
device driving circuits.

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.
Recommended testing and application 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).

*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).

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 conne ct ed to the inpu t or outp ut end in ser i es (F i gu r e 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!
