Abstract
The clock input of a buck converter is delayed, preventing sub-harmonic oscillation. The function may be achieved by implementing a clock delay generation circuit, configured to delay a next clock pulse by an amount of time directly proportional to the most recent on time of the high-side switch for peak-mode current control, inversely proportional to the most recent on time of the low-side switch for peak-mode current control, inversely proportional to the most recent on time of the high-side switch for valley-mode current control, or inversely proportional to the clock minus the most recent on time of the high-side switch for valley-mode current control.
