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 3000VDC); 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.

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, or use our company's products with a lower rated output power. Recommended 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). L L See tolerance envelope graph 0.03 150 %/C mVp-p KHz *Test ripple and noise by "parallel cable" method. See detailed operation instructions at Testing of Power Converter section, application notes. Note: 1. All specifications measured at TA=25C, humidity<75%, nominal input voltage and rated output load unless otherwise specified. 2. See below recommended circuits for more details. Vin Cin +Vo DC DC Cout GND 0V (Figure 1) 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 recommended capacitance of its filter capacitor sees (Table 1).
