Abstract: A time signal generator includes a time signal circuit and a timing circuit. The time signal circuit includes a current source and a current source circuit, and has a first mode and a second mode. The time signal generator provides a first on-time signal according to the current source in the first mode. The timing circuit is connected to the time signal circuit, and includes a first timing circuit. When the timing circuit counts to a first predetermined time, the first timing circuit provides a first control signal to the current source circuit, such that the time signal generator provides a second on-time signal according to the current source and the current source circuit in the second mode. A width of the second on-time signal is less than a width of the first on-time signal.
