Abstract
A method for reducing EMI for a frequency-modulated DC-DC converter includes pre-regulating an input voltage of the frequency-modulated DC-DC converter, so that the frequency-modulated DC-DC converter changes an operating frequency of the frequency-modulated DC-DC converter to stabilize an output voltage of the frequency-modulated DC-DC converter, so as to achieve a desired frequency extension.
