摘要： A DC-DC converter for generating power supply voltage differing from input voltage, while operating a semiconductor circuit at a predetermined speed regardless of differences between devices or changes in the operation environment. An output voltage control circuit compares an oscillation signal, which is provided from a ring oscillator of the semiconductor circuit, with a triangular wave signal, which is provided from an oscillator of the DC-DC converter, and changes the output voltage of the DC-DC converter in accordance with the comparison result. This substantially equalizes the oscillation signal of the ring oscillator with the triangular wave signal, which functions as a reference signal, and operates the semiconductor circuit at a speed that is in accordance with the triangular wave signal.

摘要： A first terminal receives an input voltage. A second terminal is connected to one end of an inductor element. A third terminal is connected to the other end of the inductor element. For example, the third terminal (the other end of the inductor element) is connected to a ground line via a capacitor element. A switch circuit connects the second terminal to one of the first terminal and a ground line. A control circuit switches a connection destination of the switch circuit according to a voltage of the third terminal in order to set the third terminal at a predetermined voltage. An internal circuit receives the voltage of the third terminal as a power supply voltage.
