APPLICATION
The WRA_S-3WR2 & WRB_S-3WR2 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. For these DC-DC converters, you can
reduce the design point of failure and save the
development of micro power supply‘s manpower, material
and time costs, also better ensure product quality stability,
protect safety and reliability of the end of products.
These products apply to where:

DESIGN CONSIDERATIONS
1) Requirement on output load
To ensure this module can operate efficiently and reliably, during operation, the minimum output load could not be less than 5% of the full load,
otherwise output ripple maybe increase dramatically. If the actual output power is very small, please connect a resistor with proper resistance at the
output end in parallel to increase the load, suppose to use the resistance of 5% rated power, or use our company’s products with a lower rated output
power.
2) Recommended circuit
All the WRA_S-3WR2 & WRB_S-3WR2 series have been tested according to the following recommended test circuit before leaving the factory
(see Figure 6).
If you want to further decrease the input/output ripple, you can increase a capacitance-values 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 must be less than the Max. Capacitive
Load.

3) Ctrl Terminal
When open or high impedance, the converter works well; When this pin is ‘high’, the converter shut down. It should be note that the input current
should be between 5-10mA, exceeding the maximum 20mA will cause permanent damage to the converter. The value of R can be derived as follows:
VC -VD -1.0
R =
-300
IC
For Detailed parameter, please refer to "EMC RECOMMENDED CIRCUIT".
4) Input current
When it is used in unregulated power supply, be sure that the fluctuating range of the power supply and the rippled voltage do not exceed the
module standard. Input current of power supply should afford the flash startup average current of this kind of DC/DC module (Figure 7).

Note:
1. Min. load shouldn't be less than 5%, otherwise ripple maybe increased dramatically. If the product operates under min. load, it may not be
guaranteed to meet all specifications listed. Operation under minimum load will not damage the converter.
2. Recommended Dual output models unbalanced load is ≤±5%, if the product operates >±5%, it may not be guaranteed to meet all specifications
listed. Please contact our technical support for more details.
3. Max. Capacitive Load is tested at input voltage range and full load.
4. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
5. In this datasheet, all test methods are based on our corporate standards.
6. All characteristics are for listed models, and non-standard models may perform differently. Please contact our technical support for more details.
7. Please contact our technical support for any specific requirement.
8. Specifications of this product are subject to changes without prior notice.
