upon the current capability of the DC/DC converter
associated with the external inductor L1 and the reservoir
capacitor connected across CRD_VCC and GROUND.
During this sequence, the average input current is 300 mA
typical (Figure 4), assuming the system is fully loaded
during the startup. Finally, the application software is
responsible for the smart card signal sequence.
