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 WRA_(M)P-3W & WRB_(M)P-3W Series have been tested according to the following
recommended testing circuit before leaving factory. This series should be tested under load.
Never be tested under no 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 (WRA_MP-3W/WRB_MP-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 excced indexes of the converter. The preceding power source must be able to provide for
converter sufficient starting current Ip (Figure 2).
General: Ip ≤1.4*Iin-max
4) No parallel connection or plug and play

Note:
1. The load shouldn't be less than 10%, otherwise ripple will increase dramatically.
2. Operation under 10% load will not damage the converter; However, they may not meet all specification listed.
3. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
4. In this datasheet, all the test methods of indications are based on corporate standards.
5. Only typical models listed, other models may be different, please contact our technical person for more details.
