Patent ID: 7589517

Claim:
An apparatus for adjusting slope compensation in a switching regulator that includes an inductor, the apparatus comprising: a divider block that is arranged to: receive a first signal, receive a second signal, and provide a divide signal that is proportional to a division of the first signal by the second signal, wherein the first signal is associated with an output voltage (V OUT ) of the switching regulator, and wherein the second signal is related to a measured value associated with the inductor; a ramp generator block that is responsive to the divide signal such that the slope of the ramp signal dynamically adjusted in response to the output voltage of the switching regulator and the measured value associated with the inductor; and a difference circuit that is arranged to: receive a first input signal (V REF ) that is associated with the output voltage (V OUT ), receive a second input signal (V IN ) that is associated with an input voltage, and provide the first signal (V DIFF ) as a difference between the first in put signal (V REF ) and the second input signal (V IN ).
