Claim Text:
1. A device, comprising: a switching converter comprising: a capacitor coupled to the output terminal; a controller configured to coordinate the first switch and the second switch to accumulate energy at the inductor and deliver the energy to an output load, wherein the output load is regulated to a defined output voltage, wherein the controller comprises an adaptive duty ratio compensator configured to stabilize the switching converter, and wherein a response of the adaptive duty ratio compensator is adjusted during a detected load transient period; a first linear regulator configured to detect an output undershoot voltage, and to source a first current to the output load and the capacitor in response to detection of the output undershoot voltage, wherein the first linear regulator comprises: a second linear regulator configured to detect an output overshoot voltage and to sink a second current of the output load and the capacitor in response to detection of the output overshoot voltage.
