Abstract
The present disclosure provides a control circuit operating in a pulse skip mode (PSM) and a voltage converter having the same, which adaptively adjust the related values in PSM through a pulse skip circuit. More specifically, the pulse skip circuit adaptively adjusts a second comparator signal indicating a second signal (related to a feedback signal with a lower gain) and/or indirectly adjusts a first comparator signal indicating a first signal (related to a feedback signal with a higher gain) to adaptively adjust the on-time of a high-side switch and the on-time of a low-side switch during PSM, thereby reducing the output current ripple.
