APPLICATIONS
The
WRD_(M)P-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.
These products apply to:
1) Where the voltage of the input power supply
is wide range (voltage range
≤2:1);
2) Where isolation is necessary between input
and output (Isolation Voltage
≤
1500VDC);
3) Where isolation is necessary between Vout1
and Vout2 (Isolation Voltage
≤
1000VDC);
4) Where the regulation of the output voltage
and the output ripple noise are dem anded.

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_(M)P-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_MP-3W). For every channel of output, provided
the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor sees
(Table 1). General:

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).
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.
