Abstract
A controller for a switching regulator includes an error amplifier configured to receive a feedback voltage indicative of the regulated output voltage and a reference voltage, and to generate an error signal indicative of the difference between the feedback voltage and the reference voltage; a loop calculator configured to generate an output signal in response to the error signal, the output signal being used by the switching regulator to generate the regulated output voltage having a voltage value related to the reference voltage; and an output voltage adjust circuit configured to receive a sense current signal indicative of a current flowing through the load and to generate a voltage adjust signal in response to the sense current signal, the voltage adjust signal being applied to generate the reference voltage relative to a predetermined set voltage.
