These products apply to: 1) where the voltage of the input power supply is fixed (voltage variation ≤±10%); 2) where isolation is necessary between input and output (isolation voltage ≤1000VDC); 3) where the regulation of the output voltage and the output ripple noise are not demanded. Such as: purely digital circuits,ordinary low frequency analog circuits,and 1GBT power device driving circuits. OUTPUT SPECIFICATIONS Parameter Test conditions Min Typ.

Filtering To get the input/output ripple,an "LC"filtering network may be connected to the input and output ends of the DC/DC converter.Which may produce a more significant filtering effect.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). 125 ℃ 300 Temp.rise at full load 15 25 Cooling Free air convection Case material Plastic(UL94-V0) Continuous Short circuit protection* 1 MTBF 3500 Weight s K hours 2.8 *Supply voltage must be discontinued at the end of short circuit duration. g 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).
