APPLICATION INFORMATION
class-D EVM power supply decoupling data
The decoupling capacitance required will depend upon the application. Pads and through-holes have been
provided on the EVM for the addition of bulk capacitance (see the schematic). A plot showing the impact of
various levels of bulk capacitance on the voltage ripple on the power supply line is shown in Figure 11. This ripple
is maximum at higher frequency. The figure shows worst-case voltage ripple for a 20-kHz, 10-W output into a
4-
Ω load. In all cases, two 10-µF and one 1-µF ceramic chip capacitors were decoupling the power supply signal
from the EVM. The 1-
µF unit was placed immediately adjacent to the IC power pins, and the 10-µF units were
placed adjacent to each other a little farther out.
The upper trace shows the ripple when only these capacitors are used. The middle trace shows the impact of
an additional 330-
µF aluminum electrolytic capacitor rated at 25 V, 90 mΩ, and for 755 mA at 100 kHz. In the
bottom trace, the 330-
µF capacitor was replaced by a 390-µF aluminum electrolytic capacitor rated at 35 V, 65
m
Ω, and for 1.2 A of 100 kHz ripple current.
The results indicate that for sensitive circuits where minimum voltage ripple is required, a larger bulk
capacitance with low ESR should be used. For systems that are contained and EMI is controlled, less
capacitance may be used. The difference in the level of distortion in the output signal was very small between
each level of decoupling, with the 20-
µF bulk capacitance providing the least distortion. This is attributed to the
low ESR of the capacitor, which is only a few milliohms at the switching frequency of 250 kHz. The distortion
is made lower still by the parallel combination. Distortion of the output signal when only one 10-
µF capacitor
is used is the same as for 20
µF. The difference is more noticeable on the power supply line, though the distortion
is increased only slightly more than with the 20-
µF capacitor.
