Note 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
=
(CPD) (V
CC
) (f
IN
)
+
(I

static).
