Abstract
A method and apparatus for controlling a step-down converter, including setting an on-state time (T) to a default T; switching, when an output voltage of the step-down converter falls below a reference output voltage, the step-down converter to an on-state for a duration of the T; and switching, at the end of the T, the step-down converter to an off-state for a minimum off-state time (T).
