SSC On/Off Comparison
Zoom In of SSC On/Off Comparison
from 1.5MHz to 150MHz
from 1.5MHz to 3.5MHz
Figure 25.
Figure 26.
Figure 25 to Figure 26 shows the advantage of SSC with the frequency spectrum centering on the nominal
frequency 2.25MHz. The blue spectrum is the result of the spread change. As depicted in the figures the
harmonic spectrum is attenuated 10dB comparing to the same device without SSC.
POWER GOOD
The open drain PG output is used to indicate the condition of the step down converter and each LDO. This is a
combined output, with the outputs being compared when the appropriate enable signal is high. The pin will be
pulled low when all enabled outputs are greater than 90% of the target voltage and High-Z when an enabled
output is less than 90% of its intended value or when all the enable signals are pulled low.
