Abstract
A control circuit, comprising a protection detection circuit, a protection synchronous output circuit, a protection synchronous input circuit and a protection circuit, is provided. The protection detection circuit is adapted to generate an error notice signal when detecting an error condition. The protection synchronous output circuit is coupled to the protection detection circuit for enabling a level of a protection synchronous pin to be a protection level when receiving the error notice signal. The protection synchronous input circuit is coupled to the protection synchronous pin for generating a synchronous protection signal when the level of the protection synchronous pin has been at the protection level for a predetermined time period. The protection circuit generates a protection signal to make the control circuit enter a protection mode when receiving one of the error notice signal and the synchronous protection signal.
