A converting controller comprises a power pin, a ground pin, at least one input pin, at least one output pin, at least one set pin and a failure generating circuit. The power pin is adapted to be coupled with a power source to receive electric power for operation, and the ground pin is adapted to be grounded. The input pin is adapted to receive a corresponding input signal and the output pin is used to output a corresponding output signal. The set pin is adapted to set a corresponding operating parameter of the converting controller. The failure generating circuit is coupled with and uses one of the input pin and the set pin as a protection output pin. The failure generating circuit modulates the level of the protection output pin to be a protection logic level when the converting controller is under a protection state.
