Abstract
A circuit includes an input to be coupled to receive a rectified line voltage having a controlled conduction phase angle in each half line cycle. An active device is coupled to a feedback terminal of a controller. The feedback terminal is coupled to receive a feedback signal representative of an output of a power supply. The active device includes a control terminal coupled to receive a signal representative of the input. The active device is coupled to adjust the feedback signal on the feedback terminal in response to the control of the conduction phase angle of the rectified line voltage in each half line cycle.
