Design Reference  
1. Recommended circuit  
All the DC/DC converters of this series are tested according to the recommended circuit (see Fig. 2) before delivery.  
If a further decrease of the input and output ripple is required, properly increase the input & output of additional capacitors Cin1, Cin2, Cs  
and Cout; or select capacitors of low equivalent impedance like series capacitor, etc. Cs is used to reduce ripple. No need to add Cs, if  
ripple meets the demand .Appropriate filter capacitance shall be chosen, start-up problems may be caused if the capacitance is too  
large. For each output circuit, under the condition of safe and reliable operation, the max. capacity of its filter capacitor should be lower  
than the max. capacitive load.

VC is the voltage of the Ctrl end relative to the GND of the input grounding; VD is the positive-going conduction pressure drop of D1; IC is the current flows  
into the Ctrl end and its value is generally 5-10mA, see Fig. 3-for the peripheral circuit of Ctrl end;  
If there is no recommended parameters, no external component is required.

3. Ctrl end  
The modules are of normal output when the Ctrl end is suspended or of high resistance; the modules turn off when connecting with high  
level (relative to the input grounding); notice that the current flows into the pin shall be 5 - 10mA, the modules will be permanently damaged  
if the current exceeds its max. value (20mA in general).  
The value of R can be derived as follows:  
VC -VD -1.0  
R =  
-300  
IC  
For Detailed parameter, please refer to EMC solution-recommended circuit in this manual.  
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 series Iave =445mA  
Vin=12V series lave =205mA  
Vin=24V series lave =104mA  
Vin=48V series lave =53mA

5. Output load requirements  
When using, the minimum load of the module output should not be less than 5% of the nominal load.In order to meet the performance  
parameters of this datasheet, please connect a 5% dummy load in parallel at the output end, the dummy load is generally a resistor, please  
note that the resistor needs to be used in derating.

1. Packing information please refer to Product Packing Information which can be downloaded from www.mornsun-power.com. Packing  
bag number: 58210004;  
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% 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;
