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 voltage1500VDC); 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: Cin: 5V&12V 24V&48V 100F 10F-47F

Cout: 10F/100mA 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: Ip 1.4*Iin-max No parallel connection or plug and play

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=25C, 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.
