A first rail enable node is coupled to the first rail control circuit and a first voltage regulator.

Abstract: The subject matter described herein provides systems and techniques for controlling the production of eNoise in an audio playback system. The eNoise may be an audible noise produced when a current, such as a noise/ripple current, flows through a battery of the audio playback system. Such eNoise may be reduced by limiting the current, such as noise/ripple current, flowing through the battery. In some examples, the noise/ripple current may be diverted to the main board of the audio playback system by adding a source of current. A circuit to produce such a current may include transistor(s), capacitor(s), and/or resistor(s). Using the current source and/or such a circuit may also divert the noise/ripple current away from the battery, thereby reducing the eNoise produced.
