AC Electrical Characteristics (Note 5)
Note 5: Refer to Timing Chart.
Note 6: 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
1*Duty/100
