CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average operating current can be obtained by the equation: ICC(OPR) = CPD VCC fin + ICC / 6 (per buffer). CPD is used to determine the no−load dynamic power consumption; PD = CPD VCC2 fin + ICC VCC.
