APPLICATIONS
The PWA_CS-2W & PWB_CS-2W Series are
specially designed for applications where a
wide range input voltage 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 wide range (voltage range4:1);
2) Where isolation is necessary between input
and output(isolation1500VDC);
3) Where the regulation of the output voltage
and the output ripple noise are demanded.

* Input voltage over it may cause permanent damage to the device.
Note: The load shouldn't be less than 10%, otherwise ripple will increase dramatically.
Operation under 10% load will not damage the converter; However, they may not meet all specification
listed.

If you want to further decrease the input/output
ripple, an LCfiltering network may be connected
to the input and output ends of the DC/DC
converter, see (Figure 1).

However, the capacitance of the output filter
capacitor must be proper. If the capacitance is too
big, a startup problem might arise. For every

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 companys products with
a lower rated output power.

When open or high impedance, the converter work well; When this pin is high; the
converter shutdown; It should be note that the input current should between
5-10mA,exceeding the maximum 20mA will cause permanence damage to the converter. The
value of R can be derived as follows:
Vc-VD-1.0
