Abstract
A voltage error signal Vis provided to a PWM controller of a voltage regular and used to produce a PWM signal that drives a power stage of the regulator. When operating in an adaptor current limit regulation mode, an adaptor current sense voltage V, indicative of an adapter current I, is compared to an adapter current reference voltage Vto produce an adapter current error signal V. A compensator receives the adapter current error signal Vand outputs a compensated adapter current error signal. The adaptor current sense voltage V, or a high pass filtered version thereof, is subtracted from the compensated adapter current error signal to produce the voltage error signal Vprovided to the PWM controller. Alternatively, an input voltage V, or a high pass filtered version thereof, is added to the compensated adapter current error signal to produce the voltage error signal V.
