Notes:
4. Refer to Timing Chart.
5. 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+ ICC1 • Duty / 100 + ICC / 2 (per Circuit)
ICC1: Active Supply Current
Duty: %
