Abstract
An apparatus and method of controlling power converters is achieved that produces high light-load efficiency and reduced output voltage ripple while maintaining quiet operation that is free from audible noise. The inventive method includes a variable on-time control circuit that is applicable to a wide variety of switching mode converters, including, but not limited to, boost converters, buck converters, buck-boost converters, single-ended primary inductor (SEPIC) converters, and other converter topologies, both isolated and non-isolated.
