APPLICATION NOTE

1) 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.

2) Recommended Circuit

All the WRD-YD-3W 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. If you want to use the products in high EMI, please choose our metal packaged

products (WRD_YD-3W). For every channel of output, provided the safe and reliable operation is ensured, the greatest

capacitance of its filter capacitor sees

3) Input Current

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 Ip (Figure 2).
