Notes: 3. CPD is defined as the value of the internal equivalent capacitance which is derived from dynamic operating current consumption (ICCD) at no output loading and operating at 50% duty cycle (see Figure 2). CPD is related to ICCD dynamic operating current by the expression: ICCD = (CPD)(VCC)(fIN) + (ICC static).
