APPLICATION NOTES
3. Trim Application And Trim Resistance (Single Output Models)
Application circuit for TRIM (Part in broken line is the interior of models)
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 VYB15W 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.
