System voltage ripple reduction

A method for supplying power, comprising:

• detecting a frequency at which a power supply circuit enters and exits (a) a current limit condition for a charger or (b) a battery supplement mode in which a battery supplements power provided to a load by the charger;
• determining whether the frequency is within a configured frequency range;
• and
• decreasing a current or voltage limit associated with the charger based on the frequency being within the configured frequency range.

An apparatus for supplying power, comprising:

• means for detecting a frequency at which a power supply circuit enters and exits (a) a current limit condition for a charger or (b) a battery supplement mode in which a battery supplements power provided to a load by the charger;
• means for determining whether the frequency is within a configured frequency range;
• and
• means for decreasing a current or voltage limit associated with the charger based on the frequency being within the configured frequency range.

An electronic device, comprising:

• a battery;
• one or more circuits;
• and
• a power supply circuit comprising:
• a charger coupled to the battery;
• a frequency detector configured to detect a frequency at which the power supply circuit enters and exits (a) a current limit condition for the charger or (b) a battery supplement mode in which the battery is configured to supplement power provided to the one or more circuits by the charger;
• a frequency comparator configured to determine whether the frequency is within a configured frequency range;
• and
• a ripple reduction circuit configured to decrease a current or voltage limit associated with the charger based on the frequency being within the configured frequency range.
