When operating in an adaptor current limit regulation mode, an adaptor current sense voltage VACS, indicative of an adapter current IA, is compared to an adapter current reference voltage VAC_REF to produce an adapter current error signal VAC_ERR. A compensator receives the adapter current error signal VAC_ERR and outputs a compensated adapter current error signal. The adaptor current sense voltage VACS, or a high pass filtered version thereof, is subtracted from the compensated adapter current error signal to produce the voltage error signal VERR provided to the PWM controller. Alternatively, an input voltage VIN, or a high pass filtered version thereof, is added to the compensated adapter current error signal to produce the voltage error signal VERR."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Voltage converters and methods for use therewith","description":"A voltage error signal VERR is provided to a PWM controller of a voltage regular and used to produce a PWM signal that drives a power stage of the regulator.
