Abstract: A high efficiency converter is provided. The converter can be used in applications requiring fast transient response under a first loading condition, and high efficiency under a second loading condition. The converter converts one or more input voltages via two or more conversion paths. Each of the two or more conversion paths corresponds to a different loading condition which indicates a magnitude of a load driven by the converter (e.g., heavy or light), and a target transient response of the load (e.g., fast or slow). A conversion path for a heavy or fast loading condition converts an input voltage directly to a target output voltage. A conversion path for a light or slow loading condition includes a two-stage architecture.

Abstract: A voltage converter is provided. The voltage converter includes a compensation circuit, a first comparator circuit, a first inductor, a first driver circuit, and a phase-lag circuit. The compensation circuit generates a first compensation signal according to a loading state of the voltage converter. The first comparator circuit compares the first compensation signal and a first reference signal to generate a first comparison signal. The first driver circuit generates a first driving voltage to the first inductor according to the first comparison signal. The phase-lag circuit is coupled between the first comparison circuit and the first driver. The phase-lag circuit modifies a duty of the first comparison signal for changing a first inductor current following the first inductor.
