Abstract:
1. A power converter, comprising: a power switch having an on state and an off state; an energy storage element coupled to transfer energy to an output of the power converter in response to the power switch switching between the on and off states; a driver coupled to control the switching the power switch, wherein the driver controls the power switch such that an input current of the power converter is substantially proportional to an input voltage of the power converter in response to an on time signal that indicates an end of an on time of the power switch and in response to an off time signal that indicates an end of an off time of the power switch; a first calculator coupled to integrate the input current to determine the end of the on time of the power switch and to output the on time signal in response thereto; and a second calculator coupled to integrate a difference between the input voltage and an output voltage of the power converter to determine an end of the off time of the power switch and to output the off time signal in response thereto.
