Note:
C_PD 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:
I_{CC (opr)} = C_PD·V_CC·f_IN + I_CC’·Duty/100 + I_CC/2 (per circuit)
(I_CC’: active supply current)
