Abstract: The present invention relates to an information processing apparatus that comprises a plurality of electric circuits and that has power supply lines for the individual electric circuits. It provides a switching regulator that controls the power that is supplied by an external power source to such an information processing apparatus, while inhibiting power waste, and the information processing apparatus and a method for its control.
The information processing apparatus, which is activated by power supplied from an external power source, comprises: a first power supply line for supplying power to a first electric circuitry; a second power supply line for supplying power to a second electric circuitry; a i-th power supply line for supplying power to a i-th electric circuitry (i is an integer of 1 ≦ i ≦ n, and n is an integer equal to 2 or greater); means for monitoring a first voltage of the first power supply line; means for monitoring a second voltage of the second power supply line; means for monitoring a i-th voltage of the i-th power supply line; means for selecting the minimum voltage among the first through the i-th voltages; means for comparing the minimum voltage with a previously given reference voltage; and connecting/disconnecting means for starting or halting the power supply from the external power source in response to the comparison result. As the lowest voltage can be used as a feedback target, the application of a high voltage is not required even if the safety of the system is taken into consideration and power will not be wasted.

Abstract: PURPOSE: To charge a battery in a short time, while supplying load with a sufficient drive current by feedback-controlling an output from a power supply, so as to reach approximately a constant power on the basis of a voltage feedback value and a current feedback value. CONSTITUTION: When the output voltage V(0) of an AC adapter 20 is made higher than the potential V(Z1) of a Zener diode(ZD) 148A, the voltage feedback value of a feedback path which passed through the ZD 148A does not reach zero, and the voltage feedback value and a current feedback value from a current-detecting resistor 114 are added by an adder 150. Accordingly, a feedback path passed through a differential amplifier 120 is worked as an approximately constant power control feedback means, and an output from the AC adapter 20 is controlled, so as to reach approximately a constant power on the basis of both the current feedback value and the voltage feedback value. The AC adapter 20 supplies a system load with a drive current, while feeding a battery with a surplus power at that time.

Abstract: PURPOSE: To suitably prevent the over-discharge of a battery in accordance with respective states, even if the operating state of an electric/electronic unit main body-side fluctuates by comparing the output terminal voltage of the battery with a threshold voltage and controlling an opening/closing means in accordance with the compared result. CONSTITUTION: An over-discharge protection circuit 40 is connected to the output terminal of a battery pack in parallel, and a period immediately before the battery becoming an over-discharged (pole change) state is detected by comparing a terminal voltage VBATT with a threshold voltage. Thus, an FET switch SW1 is on/off-controlled. Furthermore, the over-discharge protection circuit 40 discriminates the operating state of a personal computer system by monitoring a sub-power line VCCSB and correspondingly and dynamically adjusts the self-threshold. Consequently, the over-discharge of the battery can be suitably prevented according to the respective states, even if the operation state of the electric/electronic unit main body-side of the personal computer system fluctuates.

Abstract: PURPOSE: To provide a switching regulator, an information processor and the control method for controlling power supply from an external power source to the information processor, without dissipating wasteful power with an information processor constituted of plural electric circuit systems and provided with power supply lines for the respective electric circuit systems as an object. CONSTITUTION: This information processor, which is driven by supplied power from the external power source, is provided with a means 51 for selecting a minimum voltage from first - (n)-th power supply lines, the means for comparing the minimum voltage with a reference voltage set beforehand and a connection/interruption means 23 for starting or interrupting the supply of the power from the external power source, corresponding to the result of a comparison. Also, since the lower voltage is used as the object of feedback, the need for applying for a higher voltage in anticipation of the maintenance of a system is eliminated, and the wasteful power does not need to the supplied.
