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 WRA_ZD-8W&WRB_ZD-8W Series have been tested according to  
the following recommended testing circuit before leaving factory.This series  
should be tested under 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 should not be too high, or may cause start-up problem.

Output External Capacitor Table(Table 1)  
While using unstable power source,please ensure the output voltage and  
ripple voltage do not exceed indexes of the converter.The preceding power  
source must be able to provide for converter sufficient starting current
