The switching circuitry is configured to cause a charging current to flow until the charging current has a predetermined relationship to a threshold, and to cause a discharging current to flow after the charging current. The adjuster circuit is configured to adjust the threshold in response to at least one of a charging period during which the charging current flows and a discharging period during which the discharging current flows. For example, a power supply may include such a power-supply controller to maintain a length of a current pulse, or of a portion thereof, within a particular range, such as approximately at a particular value, during a pulse-frequency-modulation (PFM) mode despite variations in one or more parameters such as input voltage, output voltage, filter capacitance, phase inductance, charging-current-sense impedance, and load, from their respective nominal values."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Adjusting a current threshold of a power supply in response to a portion of a current-pulse period","description":"An embodiment of a power-supply controller includes switching circuitry and an adjuster circuit.
