APPLICATIONS
The MSA_(M)D-3W &MSB_(M)D-3W 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 the regulation of the output voltage and
the output ripple noise are dem anded.

APPLICATION NOTE
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.
Recommended Circuit
All the MSA_(M)D-3W & MSB_(M)D-3W Series have been tested according to the following
recommended testing circuit before leaving factory. This series should be tested under load.
Never be tested under no 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 of the output filter capacitor must
be proper. If the capacitance is too big, a startup problem might arise. For every channel of
output, provided the safe and reliable operation is ensured, the greatest capacitance of its filter
capacitor sees (Table 1). Generally: If you want to use the products in high EMI, please choose
our metal packaged products (MSA_MD-3W & MSB_MD- 3W). General:

Input Current
When it is used in unregulated power supply, be sure that the fluctuating range of the power
supply and the rippled voltage do not exceed the module standard. Input current of power
supply should afford the startup current of this kind of DC/DC module (See figure 2), General:

Note:
1. The load shouldn't be less than 10%, otherwise ripple will increase dramatically.
2. Operation under 10% load will not dam age the converter; However, they may not meet all specification listed.
3. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
4. In this datasheet, all the test methods of indications are based on corporate standards.
5. Only typical models listed, other models may be different, please contact our technical person for more details.
