Design Reference
1. Output load requirements
To ensure that the module can work efficiently and reliably, its output min. load shall be no lower than 5% of the rated load when using, or
the output ripple may increase rapidly. Ensure that the product working load must be higher than 5% of the rated load.
2. Typical application
All the DC/DC converters of this series are tested according to the recommended circuit (see Fig. 2) before delivery.
If it is required to further reduce input and output ripple, properly increase the input & output of additional capacitors Cin and Cout or
select capacitors of low equivalent impedance provided that the capacitance is no larger than the max. capacitive load of the product.

4. Input current
When the electricity is provided by the unstable power supply, please make sure that the range of the output voltage fluctuation and the
ripple voltage of the power supply do not exceed the indicators of the modules. Input current of power supply should afford the flash startup
current of this kind of DC/DC module(see Fig. 5).
Generally: Vin=5V

Dimensions and Recommended Layout
Notes:
1. Packing information please refer to Product Packing Information which can be downloaded from www.mornsun-power.com. Packing
bag number: 58210008;
2. Recommend to use module with more than 5% load, if not, the ripple of the product may exceeds the specification, but does not
affect the reliability of the product;
3. The recommended unbalance degree of the dual output module load is ≤±5%; if the degree exceeds ±5%, than the product
performance cannot be guaranteed to comply with all parameters in the datasheet. Please contact our technicians directly for
specific information;
4. The maximum capacitive load offered were tested at nominal input voltage and full load;
5. Unless otherwise specified, parameters in this datasheet were measured under the conditions of Ta=25℃, humidity<75%RH with nominal
input voltage and rated output load;
6. All index testing methods in this datasheet are based on Company’s corporate standards;
7. The performance parameters of the product models listed in this manual are as above, but some parameters of non-standard model
products may exceed the requirements mentioned above. Please contact our technicians directly for specific information;
8. We can provide product customization service;
9. Specifications are subject to change without prior notice.
