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.
