APPLICATIONS
The B_XD-1W Series is specially designed
for applications where a single power supply
is 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
demanded.
Such as: purely digital circuits, ordinary low
frequency analog circuits.
These products don’t apply to:

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.

OUTLINE DIMENSIONS& RECONMENDED FOOTPRINT DETAILS
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 (see Figure 2).

APPLICATION NOTE
Filtering
For some circuits which are sensitive to noise and ripple, a filtering capacitor
may be added to the DC/DC output end and input end to reduce the noise and
ripple. However, the capacitance of the output filter capacitor must proper. If
the capacitance is too big, a startup problem might arise. For every channel of
output, providing the safe and reliable operation is ensured, the greatest
capacitance of its filter capacitor refer to the External Capacitor Table. To get
an extreme low ripple, an “LC” filtering network may be connected to the input
and output ends of the DC/DC converter, which may produce a more
significant filtering effect. 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 (see figure 1).
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! 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 (B_XD -0.25W series).
