Abstract
In one embodiment, an apparatus includes a controller to control a voltage regulator. The controller may have a first comparator circuit to compare a first reference voltage to a feedback voltage. In turn, the first comparator circuit may include: a first comparator having a first input terminal to receive the feedback voltage and a second input terminal to receive the reference voltage and an output node to output an error signal based on the comparison; and a first pre-charge circuit coupled between the first input terminal and the output node configured to pre-charge a first portion of a compensation network to a pre-charge level. The first controller may further include a second comparator circuit coupled to the first comparator circuit compare the error signal to a ramp signal and to generate a first control output to control a power train of the voltage regulator in a first mode of operation.
