ABSTRACT:
Switching losses in a DC-to-DC converter idling in a pulse-skipping mode are reduced by inhibiting any intervening turn-off command by a PWM control loop of the converter for as long as the current through the inductor of the converter remains below a minimum threshold value set by a dedicated comparator. The method is implemented by employing a comparator with a certain hysteresis and by logically masking the switching to a logic "0" of a high frequency clock (switching) signal of the converter for the entire period of time the current in the inductor remains below the minimum threshold.
