An example integrated circuit controller for a power converter includes a digital peak detector and a switching block. The digital peak detector is coupled to output a digital count signal representative of a peak input voltage of the power converter. The switching block is coupled to control switching of a power switch of the power converter to regulate an output of the power converter. The switching block is further coupled to control the switching of the power switch in response to the digital count signal. |
