Abstract
An example controller for a power converter according to aspects of the present invention includes a switching control that switches a power switch to regulate an output of a power converter. The controller also includes a sensor coupled to receive a signal from a single terminal of the controller. The signal from the single terminal is representative of a line input voltage of the power converter during at least a portion of an on time of the power switch. The signal from the single terminal is also representative of an output voltage of the power converter during at least a portion of an off time of the power switch. The switching control is responsive to the sensor.
