Notes:
3. C
PD
is defined as the value of the internal equivalent capacitance which is derived from dynamic operating current consumption
(I
CCD
) at no output loading and operating at 50% duty cycle (see Figure 2). C
PD
is related to I
CCD
dynamic operating current by
the expression: I
CCD
= (C
PD
)(V
CC
)(f
IN
) + (I
CC
static).
