APPLICATIONS
The MD_XD-6W 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 fixed
voltage range;
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.

Converter section, application notes.
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
appropriate resistor as extra loading, or contact our company for other lower output power products.
2) Recommended Circuit
All the MD-XD-6W 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
an
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:

Cout: 10µF/100mA

EXTERNAL CAPACITOR TABLE (TABLE 1)
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
