APPLICATION NOTES
Requirement on Output Load
In order to ensure the product operates efficiently and reliably, make sure the specified range of input voltage is not exceeded and the
minimum output load is not 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.

Recommended Circuit
The VYB10W series has been tested according to the following recommended testing circuit. This series should be tested under load.

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

Notes:
1. Operation under minimum load will not damage the converter; however, they may not meet all specifications listed.
2. All specifications measured at: Ta=25°C, humidity<75%, nominal input voltage and rated output load, unless otherwise specified.
3. No parallel connection
