APPLICATIONS
8
The B_S-W2/B_D-W2 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.

2.*Designing.
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.

APPLICATION NOTE
RECOMMENDED CIRCUIT
1) Requirement on output load
L
L
+Vo
0V
To ensure this module can operate efficiently and reliably, During operation, the
minimum output load could not be less than 10% of the full 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.

2) 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).
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. It’s not recommended to connect any external capacitor in the
application field.

3) 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).
4) 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.
5) No parallel connection or plug and play

Note:
1. Operation under minimum load will not damage the converter; However, they may not meet all specification listed, and that will reduce the
life of product.
2. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
3. Only typical models listed, other models may be different, please contact our technical person for more details.
4. In this datasheet, all the test methods of indications are based on corporate standards.
