OUTPUT SPECIFICATIONS Item Overload Protection Under normal operating conditions, the output 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 TYPICAL CHARACTERISTICS 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).
