Abstract
A method of a controller of a switching power converter that provides a configurable power factor control method for the switching power converter. The controller combines power regulation control methods of constant on-time control and constant power control to adjust the power factor of the switching power converter. The controller switches between constant on-time control and constant power control based on an input voltage of the power converter.
