Abstract:
A method is for reducing power dissipation in a switching amplifier. The method may include comparing a load current with a ripple current and, if the load current is greater than the ripple current, then detecting a first potential value at a first output terminal of the switching amplifier, detecting a second potential value at a second output terminal of the switching amplifier, detecting a third potential value between first and the second terminals of a first capacitor, and coupling the first terminal of the first capacitor to one of the first output terminal and the second output terminal. The second terminal of the first capacitor may be coupled to a reference voltage, the first output terminal, or the second output terminal based upon whether the first potential value or the second potential value is equal to the third potential value.
