COMMON SPECIFICATIONS
Requirement On Output 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
recommended testing circuit before leaving factory. This series should be tested under load.
Never be tested under no load (see Figure 1).
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

APPLICATION NOTE
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:
No parallel connection or plug and play
In order to ensure the product operate efficiently and reliably, in addition to a max load
All the MSA_(M)D-3W & MSB_(M)D-3W Series have been tested according to the following
If you want to further decrease the input/output ripple, you can increase capacitance properly
