APPLICATIONS
Where the voltage of the input power
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.

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
