Based on the experiments carried out during the
NCN6000 characterization, the best comprise, at time of
printing
this
document,
6.8 F/10 V/Ceramic/X7R capacitor in parallel to achieve
the CRD_VCC filtering. The ESR will not extend 50 m
over the temperature range and the combination of standard
parts provide an acceptable –20% to +20% tolerance,
is
to
use
two
together with a low cost. Obviously, the capacitor must be
SMD type to achieve the extremely low ESR and ESL
necessary for this application. Figure 21 illustrates the
CRD_VCC ripple observed in the NCN6000 demo board
depending upon the type of capacitor used to filter the output
voltage.

The high ripple pulse across CRD_VCC is the consequence
of the large ESR of the electrolytic capacitor.
