Abstract
This thesis develops a spread spectrum switching system for DC-DC converters operating in burst mode. Burst mode DC-DC converters have high efficiency under low-power conditions in applications such as cell phones and notebook computers, but often produce noise in the audible range. This thesis explores a frequency modulation scheme and transient control that attenuates audible noise harmonics while minimizing the tradeoff for converter regulation, efficiency, and output voltage ripple.
