摘要： According to an embodiment, a direct current to direct current (DC-to-DC) converter includes a power stage, a generating circuit, a voltage dividing circuit, a subtractor and a controller. The power stage converts an input voltage to a first output voltage. The generating circuit generates a reference voltage by selecting one of candidate voltages in accordance with a level of the first output voltage. The voltage dividing circuit divides the first output voltage to obtain a second output voltage. The subtractor calculates a differential voltage between the reference voltage and the second output voltage. The control circuit generates a control signal to control the level of the first output voltage based on the differential voltage.

摘要： A DC-DC converter converts an input voltage into an output voltage and includes an input terminal, an output terminal, a power stage, a switch driving circuit, a charge pump, and a capacitor. The power stage includes a high-side switch, a low-side switch and an inductor. The switch driving circuit generates a high-side switch driving signal and a low-side switch driving signal. The charge pump generates a first polarity current according to the high-side switch driving signal, and generates a second polarity current having an opposite polarity to the first polarity current according to the low-side switch driving signal. The capacitor generates a first voltage by integrating the first and second polarity currents generated by the charge pump. The switch driving circuit generates the high-side switch driving signal and the low-side switch driving signal according to a difference between the first voltage and a reference voltage.

摘要： According to one embodiment, a power circuit includes a DC-DC converter and an activation control circuit. The DC-DC converter converts input voltage into voltage that is different from the input voltage. The activation control circuit sends a first enable signal to start operation of the DC-DC converter when voltage depending on the input voltage becomes equal to or higher than a first threshold voltage, and sends a second enable signal to start operation of a load connected to an output side of the DC-DC converter when the voltage depending on the input voltage becomes equal to or higher than a second threshold voltage. The second threshold is higher than the first threshold voltage.
