A charge control device includes a switching regulator that charges a capacitor with electricity supplied from a power supply. The charge control device is characterized in that feedback unit that feedback-inputs a predetermined control amount to the switching regulator is provided, and the switching regulator includes a control unit that controls a charge current supplied to the capacitor in accordance with the control amount feedback-input from the feedback unit.

Charge control device

There is provided a switching regulator configured to convert an input voltage into an output voltage. A control unit is configured to perform switching control in response to a result of comparison between a reference voltage and a complex voltage which includes a feedback voltage acquired by feeding back the output voltage, and a derived voltage derived on the basis of an input current.

Switching regulator, electronic device, and electronic circuit

A device control apparatus according to an embodiment includes a monitoring unit, a first processing unit, and a second processing unit. The monitoring unit monitors a state of voltage supply from a battery. When the start of the voltage supply is detected, the first processing unit starts the voltage supply to some devices, operates in a first operation mode, and executes a resume process of the devices. When the resume process is completed, the second processing unit starts the voltage supply to devices other than some devices, initializes states of the devices, and operates in a second operation mode in which consumption power is larger than consumption power of the first operation mode.
