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 demanding. Such as:purely digital circuits, ordinary low frequency analog circuits,and IGBT power device driving circuits. Test conditions Flash tested for 1 minute and 1mA max Test at Viso=500VDC Min. Typ.

The simplest method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit. Recommended testing and application circuit If you want to further decrease the input/output ripple, an “LC” filtering network may be connected to the input and output ends of the DC/DC converter, see (Figure 1). 25 Cooling Free air convection Case material Plastic(UL94-V0) Continuous Short circuit protection* 1 MTBF 3500 Weight s K hours 2.1 g *Supply voltage must be discontinued at the end of short circuit duration. TYPICAL CHARACTERISTICS 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. 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).
