Abstract
According to an exemplary embodiment, a method includes the step () of driving a buck section of a DC/DC converter with a buck signal that has a buck duty cycle and concurrently with driving the buck section, driving a boost section of the DC/DC converter with a boost signal that has a boost duty cycle, a difference existing between the buck duty cycle and the boost duty cycle. The method also includes the step () of monitoring an input voltage that is coupled to the buck section for a change in the input voltage, and in response to a change in the input voltage, the step () of changing the buck duty cycle and the boost duty cycle such that the difference between the buck duty cycle and the boost duty cycle is substantially constant.
