APPLICATIONS
The WRA_YMD-3W & WRB_YMD-3W Series are
specially designed for applications where a wide
range input voltage power supplies are isolated from
the input power supply in a distributed power supply
system on a circuit board.

APPLICATION NOTE
Requirement on output load
Input Voltage (V)
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.

All the WRA_YMD-3W & WRB_YMD-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 of the output filter capacitor must
be proper. If the capacitance is too big, a startup problem might arise. For every channel of
output, provided the safe and reliable operation is ensured, the greatest capacitance of its filter
capacitor sees (Table 1). General:
Cin:
5V&12V
100μF
24V&48V
10μF-47μF
Cout: 10μF/100mA
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). General: Ip ≤1.4*Iin-max
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.
