摘要： An electronic device includes a load device and a power management integrated circuit. The power management integrated circuit is configured to calculate a load power value and provide the load power value to the load device in response to a request from the load device. The power management integrated circuit includes a plurality of regulators and a controller. Each of the plurality of regulators includes a current meter for measuring a load current value to be provided to the load device, and the controller is configured to calculate the load power value by using the load current value measured by the current meter and a load voltage value provided from each of the plurality of regulators to the load device.

摘要： A DC-DC converter is provided. The DC-DC converter includes at least one converter circuit configured to include an inductor and to supply a current to a load through the inductor; and a controller configured to sense the current to generate a sensed signal, to sample and hold the sensed signal at a predetermined sampling time to detect an average current of the inductor, and to control an operation of the at least one converter circuit according to the average current. The sampling time is set to a time in a period while the inductor current is less than a peak and greater than a valley.
