  • Patent number: 10033280
    Abstract: [Object] To reduce power consumption of a DC-DC converter. [Solution] A voltage conversion circuit includes a voltage generation unit, a stop control unit, a current supply unit, and an intermittent control unit. The voltage generation unit generates an output voltage on the basis of a current when the current is supplied. The stop control unit outputs a signal for stopping the supply of the current. The current supply unit supplies the current to the voltage generation unit until the signal is output. The intermittent control unit operates the stop control unit during a supply period of the current and stops the stop control unit when the signal is output.
