Oscilloscope Lin Cin Lin(4.7µH) Current Probe DC DC Load Cin(220µF, ESR < 1.0Ω at 100 KHz) 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 WRE_S-3WR2 & WRF_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.

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: R= VC - VD - 1.0 - 300 IC For Detailed param eter, please refer to "EMC RECOMMENDED CIRCUIT". Input Current(A) 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).
