Abstract
In a time control circuit, a capacitor is connected between a connecting pin and a ground. A first current source supplies a first current to the connecting pin. A first comparator element has a non-inverse terminal connected to a voltage of the capacitor and a pre-set first reference voltage, and controls the initial startup time. A second comparator element has an inverse terminal connected to the voltage of the capacitor and a pre-set second reference voltage, and controls the soft start time. Further, a current bypass controller includes a current bypass path between the connecting pin and the ground, which connects the current bypass path after the soft start time and blocks it at an input of a protective signal. Additionally, a third comparator element has an inverse terminal connected to the voltage of the capacitor and a pre-set third reference voltage, and controls the shutdown time.
