Abstract
A pulse-width-modulated switching power converter is provided in which a comparator has a boosted speed to determine a trip point at which a ramp signal equals an error signal. In a linear comparator embodiment, a one-shot bias boosting circuit triggers an increased bias current to the linear comparator to boost the speed to determine the trip point. In a sense-amplifier-based comparator embodiment, a clock generator enables the sense-amplifier-based comparator prior to the trip point.
