Multiple smart card slot interface IC

[1]

Refer to Section 8.6 for further information about the DC-to-DC converter operation.

[2]

Typical value measurement based on a 85 % DC-to-DC converter and inductance efficiency; depends on PCB layout and external

component quality (inductor, capacitor).

[3]

Maximum value measurement based on a 125 mA (sum of all card supply currents on pins VCC(n)) current load and a 75 % DC-to-DC

converter and inductance efficiency; depends on PCB layout and external component quality (inductor, capacitor).

[4]

Two ceramic multilayer 100 nF (minimum) capacitors with a low Equivalent Series Resistance (ESR) should be used to meet these

specifications.

Output voltage to the card including ripple.
