Title:
SWITCHING FREQUENCY JITTERING METHOD, SWITCHING CIRCUIT, AND DC-DC CONVERTER
Document Type and Number:
WIPO Patent Application WO/2021/212664
Kind Code:
A1
Abstract:
Disclosed are a switching frequency jittering method, a switching circuit, and a DC-DC converter. In the switching frequency jittering method disclosed in the embodiments of the present application, a switching frequency jitters up and down at a third switching frequency or jitters up and down between randomly generated target switching frequencies. Further provided are a switching circuit and a DC-DC converter, which can be used to control a clock signal. Comprehensive system performance aspects of improving the system efficiency, reducing noise, reducing ripples, suppressing the switching of harmonic waves, reducing electromagnetic radiation, etc. are optimized.
