Abstract
A switching DC-to-DC converter, in which the control circuit of the switch is powered by an adaptively regulated voltage. A voltage regulator that provides the adaptively regulated voltage has a first receiving terminal coupled to an input terminal of the switching DC-to-DC converter, a second receiving terminal coupled to an output terminal of the switching DC-to-DC converter, and a regulated output terminal coupled to the control circuit to provide the adaptively regulated voltage to power the control circuit and thereby to generate a load current. According to the load current, the voltage regulator controls whether to use the output voltage to assist in the generation of the adaptively regulated voltage.
