发明名称 DC-DC CONVERTER AND SEMICONDUCTOR INTEGRATED CIRCUIT
摘要 PROBLEM TO BE SOLVED: To provide a DC-DC converter that allows achieving high-speed clock operation and high-speed load variation response while achieving high efficiency.SOLUTION: A DC-DC converter includes: a reference-voltage generating circuit generating a reference voltage; a modulating clock signal generating circuit generating a modulating clock signal; a modulator outputting a reference signal obtained by applying modulation in synchronization with the modulating clock signal to the reference voltage; a first comparator comparing the reference signal with a first feedback signal on the basis of an output voltage, and outputting a signal on the basis of the comparison result; and a driver wave-forming a PWM signal on the basis of a signal outputted from the first comparator, and outputting the resultant signal to a control node.
