APPLICATION NOTES
Requirement on Output Load
In order to ensure the product operates effi ciently and reliably, make sure the specifi ed 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 specifi ed minimum load, the output ripple may
increase sharply while its effi ciency 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.
(see Figure 1)
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.
General:
Remote On/Off
When open or high impedance,the converter will be on; When this pin is ‘high’; the converter will shutdown; It should be noted that
the input current (Ic) should between 5 ~ 10 mA, exceeding the maximum 20 mA will cause permanent damage to the converter.
The value of R Can be derived as follows :
Input Current
When using an unstable power source, please ensure the output voltage and ripple voltage do not excced indexes of the converter.
The preceding power source must be able to provide for converter suffi cient starting current Ip.
General: Ip ≤1.6*Iin-max
No parallel connection or plug and play
