The error amplifier inputs a voltage signal corresponding to an output voltage of a DC/DC result and a plurality of reference voltage signals.

The error amplifier amplifies a difference between the voltage signal corresponding to the output voltage of a DC/DC result and a voltage signal of a lower potential among the plurality of reference voltage signals and, based on-the amplified output, carries out the pulse width modulation control. Furthermore, the control circuit includes a circuit for discharging charges corresponding to the output voltage of the DC/DC result when a power supply to the control circuit is turned off. By the constitution, it is possible to easily realize power turn-on/turn-off sequence controls without requiring any special logic circuit, and thus to control rise/fall characteristics of the output voltage without depending on the load.

摘要： A DC-to-DC converter circuit having a power saving mode, and which achieves a high conversion efficiency without using a sense resistance. The DC-to-DC converter circuit includes a triangular wave generation circuit to generate a triangular wave signal and a differential amplifier to receive the triangular wave signal and to generate an output signal. A main switching element is provided to turn ON and OFF an input voltage, and a synchronous commutating switching element is provided to perform synchronous commutation of a load current. A detection device detects whether an output voltage of the main switching element is larger than an input voltage of the main switching element. A control device operates in a power saving mode to reduce a drive voltage of the main switching element in response to the detection device detecting that the output voltage of the main switching element is larger than the input voltage.

摘要： In a power supply apparatus including a plurality of batteries and a plurality of power supply portions for connecting to loads, a plurality of switches connect these batteries to these power supply portions, respectively. The apparatus further includes a control mechanism which controls the opening and closing operations of the switches. When one of the switches is turned on in one of the power supply means, the control mechanism executes the control in such a manner that the other switches are turned off. The control mechanism further controls each of the switches on the basis of the remaining capacity of each battery and the load state of each power supply portion. Accordingly, the power supply operation can be flexibly carried out.
