An audio power conversion system includes a power supply having a positive supply rail and a negative supply rail for supplying power to a single ended class D amplifier. The system further includes a supply pump reduction circuit connected to the supply rails and adapted to redistribute a pumping charge from said power supply by forcing a current-flow from a rail with a higher voltage to a rail with a lower voltage. According to the at least one embodiment of the invention, the redistribution circuit is arranges to always distribute charge from the rail with the higher voltage. Thus, for practical circuits, the pump canceling occurs continuously and is not confined to every other cycle. |
