7. Frequency Modulation
: EMI reduction can be accom-
plished by modulating the switching frequency of a SMPS.
Frequency modulation can reduce EMI by spreading the
energy over a wider frequency range. The amount of EMI
reduction is directly related to the level of modulation
(Fmod) and the rate of modulation. As can be seen in Figure
14, the frequency changes from 130kHz to 138kHz in 4mS
for the FSD200/FSD210. Frequency modulation allows the
use of a cost effective inductor instead of an AC input mode
choke to satisfy the requirements of world wide EMI limits.
