Abstract:
1. A controller for use in a power converter, the controller comprising: a switching control configured to generate a first signal to be coupled to control switching of a power switch of the power converter between a first state and a second state to regulate an output of the power converter; and a sensor coupled to receive a second signal from a single terminal of the controller during at least a portion of the time that the power switch is in the first state and during at least a portion of the time that the power switch is in the second state, wherein the second signal is representative of a line input voltage of the power converter during at least the portion of time that the power switch is in the first state, wherein the second signal is representative of an output voltage of the power converter during at least the portion of time that the power switch is in the second state, and wherein the sensor is further coupled to be responsive to the first signal.
