L L TYPICAL CHARACTERISTICS +Vo Vin DC DC C C 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. It’s not recommended to connect any Operating Temp.(oC) external capacitor in the application field .
