Design Reference
1. Typical application
If it is required to further reduce input and output ripple, a “LC” filter capacitor can be connected to the input and output terminals, see
Fig.3.
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.
