current as depicted Figure 22 and the magnetic core must
sustain this level of current without damage. In particular,
the ferrite material shall not be saturated to avoid
uncontrolled current spike during the charge up cycle.
interface shall limits the CRD_VCC output current to 200
mA maximum, under short circuit conditions. The
NCN6001 supports such a parameter, the limit being
depending upon the input and output voltages as depicted in
Figure 23.
During the operation, the inductor is subject to high peak

Moreover, since the DC/DC efficiency depends upon the
losses developed into the active and passive components,
selecting a low ESR inductor is preferred to reduce these
losses to a minimum.

matter of fact, the output current limit is reduced when the
temperature increases: see Figure 24.
