APPLICATIONS
The WRD_YKD-5W 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 range≤2:1);
2)Where isolation is necessary between input and
output (Isolation Voltage≤1500VDC);
3)Where isolation is necessary between Vout1 and
Vout2 (Isolation Voltage≤1000VDC);
4)Where the regulation of the output voltage and the
output ripple noise are demanded.

APPLICATION NOTE
1) Requirement On Output Load
In order to ensure the product operate efficiently and reliably, in addition
to a max load (namely full load), a minimum load is specified for this kind
of DC/DC converter. Make sure the specified range of input voltage is not
exceeded, the minimum output load no less than 10% load. If the actual
load is less than the specified minimum load, the output ripple may increase
sharply while its efficiency and reliability will reduce greatly. If the actual
output power is very small, please add an appropriate resistor as extra
loading, or contact our company for other lower output power products.
2) Recommended Circuit
All the WRD-YKD-5W Series have been tested according to the following
recommended testing circuit before leaving factory. This series should be
tested under load (see Figure 1).
If you want to further decrease the input/output ripple, you can increase
capacitance properly or choose capacitors with low ESR. However, the
capacitance should not be too high, or may cause start-up problem. If you
want to use the products in high EMI, please choose our metal packaged
products. For every channel of output, provided the safe and reliable
operation is ensured, the greatest capacitance of its filter capacitor sees
(Table 1). General:
Cin: 5V,12V
100µF
24V&48V 22µF/10µF
Cout: 10µF/100mA
3) Input Current
While using unstable power source, please ensure the output voltage
and ripple voltage do not exceed indexes of the converter. The preceding
power source must be able to provide for converter sufficient starting
current Ip (Figure 2).
General: Ip≤1.4*Iin-max
4) No parallel connection or plug and play
