APPLICATION NOTES  
1. Requirement on Output Load  
In order to ensure the product operates efficiently and reliably, make sure the specified range of input voltage is not exc
minimum output load is not less than 10% load. If the actual load is less than the specified minimum load, the output
increase sharply while its efficiency and reliability will reduce greatly. If the actual output power is very small, please ad
appropriate resistor as extra loading.  
2. Recommended Circuit  
The VYB10W series has been tested according to the following recommended testing circuit. This series shod be teed under lod.

If you want to further decrease the input/output ripple, you can increase capacitancproperly ose capacitors with low ESR. If  
the capacitance is too big, a startup problem might arise. The maximum allwable cacitance to ensure safe and reliable operation is  
listed in Table 1.

3. Remote On/Off  
When open or high impedance,the converter will be n; When s is ‘high’; the converter will shutdown; It should be noted that  
the input current (Ic) should between 5 ~ 10 mA, excding the maximum 20 mA will cause permanent damage to the converter.  
The value of R Can be derived as follows :  
C - VD - 1.0  
R =  
IC  
4. Input Current  
When using an unstable poer source, plee the output voltage and ripple voltage do not excced indexes of the converter.  
The preceding power sourmust be able to provide for converter sufficient starting current Ip.  
General: Ip ≤1.6*Iin-max  
5. No parallel coection or pg and lay
