During the operation, the inductor is subject to high peak
current as depicted Figure 21 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.
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.
Test Conditions: Input VCC voltage = 5.0 V
Current = 200 mA/div
Tamb = +20
°
C
Figure 21. Typical Inductor Current
According to the ISO7816-3 and EMV specifications, the
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 22.
On the other hand, the circuit is designed to make sure no
over current exist over the full temperature range. As a
matter of fact, the output current limit is reduced when the
temperature increases: see Figure 23.
