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
NCN6004A supports such a parameter, the limit being
depending upon the input and output voltages as depicted
in Figure 22.

environment. As a matter of fact, this pulse does not come
solely from the NCN6004A DC/DC converter, but the
reservoir capacitor and the associated PCB tracks shall be
considered as well.

Beside the continuous current capability, the smart card
power supply must be capable of providing a 100 mA pulsed
current during the data transaction. The ISO7816-3,
paragraph 4.3.2, defines this 400 ns pulse as a function of the
