Output Capacitors (C5 and C6)
The value and ESR of this capacitor are directly linked to
the ripple of the regulated output voltage. As the charge
pump must provide up to 450 mA to the internal audio
amplifier, two 10
mF/6.3 V capacitors (0603 size) should
allow the converter to give its maximum output power
capability.
Layout Recommendations
As all switching devices, special care must be observed in
routing power supplies and ground.
VDD pins must be decoupled by C1 and C2 placed as close
as possible to the NCP2830 in order to reduce parasitic
inductance.
GND pins must be connected to a ground plane. In order
to reduce parasitic elements, it is better to connect all the
ground pins to the same Ground plane.
Figure 27. Recommended PCB Layout
Optional Output Filters
If the traces between the amplifier and the speaker are
short, there’s no need for an output filter.
In case of applications where short output traces are not
possible, it is necessary to protect the application as much as
possible from EMI pollution. The use of small 0603 Chip
Ferrite beads is a good alternative.

Thermal Considerations
For thermal dissipation, it is recommended to connect the
exposed pad of the NCP2830 to a plan connected to the
ground as depicted Figure 27.

device in typical application.
