These products apply to: 1) where the voltage of the input power supply is fixed (voltage variation ≤±5%); 2) where isolation is necessary between input and output (isolation voltage ≤3000VDC); 3) where the regulation of the output voltage and the output ripple noise are demanded.

It should also be noted that the inductance and the frequency of the "LC"filtering network should be staggered with the DC/DC frequency to avoid mutual interference see (Figure 1).

TYPICAL CHARACTERISTICS In some circuits which are sensitive to noise and ripple.a filtering capacitor may be added to the DC/DC output end and input end to reduce the noise and ripple. 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).

Requirement on output load To ensure this module can operate efficiently and reliably, a minimum load is specified for this kind of DC/DC converter in addition to a maximum load(namely full load).During operation, make sure the specified range of input voltage is not exceeded,the minimum output load is not less than 10% of the full load, and that this product should never be operated under no load! Use dual output simultaneously, forbid opening output pin (0V) to use as single output.
