Abstract
A PWM controller detecting temperature and AC line via a single pin and a power converter using the PWM controller, the PWM controller comprising: an output pin for providing a PWM signal; and a dual-function pin for receiving a temperature signal when the PWM signal is at a high level, and for receiving an AC line signal when the PWM signal is at a low level.
