Abstract
An output voltage controller includes a first controller which controls current supply to a inductor based on an output voltage, and a second controller which controls current supply to the inductor by controlling a period when an input end to which an input voltage is inputted, the inductor, and an output end from which the output voltage is outputted are coupled based on the input voltage.
Claims15
An output voltage controller comprising:
- a first controller which controls a current supply to an inductor based on an output voltage;
- and
- a second controller which controls a current supply to the inductor by controlling a period when an input end to which an input voltage is inputted, the inductor, and an output end from which the output voltage is outputted, are coupled based on the input voltage.
An output voltage control method comprising:
- controlling current supply to a inductor based on an output voltage;
- and
- controlling current supply to the inductor by controlling a period when an input end to which an input voltage is inputted, the inductor, and an output end from which the output voltage is outputted are coupled based on the input voltage.
An electronic device comprising:
- an output voltage controller,
- wherein the output voltage controller comprises
- a first controller which controls power supply to a inductor based on an output voltage and
- a second controller which controls current supply to the inductor by controlling a period when an input end to which an input voltage is inputted, the inductor, and an output end from which the output voltage is outputted are coupled based on the input voltage.
