Abstract
Mitigation of audible output of one or more components in a charging circuit. A charging circuit may include a mitigation controller operative to monitor a frequency of voltage at an input of a charging circuit. The frequency of the voltage at the input node may result in a mitigation condition associated with audible output of one or more components of the charging circuit. In response to detection of the mitigation condition, the mitigation controller may temporarily disable the supply of power from charging circuit to a system load to mitigate (e.g., potentially eliminate) audible output of the circuit. During a time in which the charging circuit is disabled from supplying power to the system load, a battery of the device may supply power to the system load.
