摘要： A direct current output voltage is switched by two switching units and a current alternately changing directions is supplied to a primary winding of a transformer. An alternating voltage induced in a secondary winding of the transformer is rectified and smoothed, and is applied to a control circuit. A bidirectional switching unit is connected in parallel with the primary winding, and is controlled by the control circuit so that the primary winding is short-circuited by the bidirectional switching unit and an exciting energy of the transformer is held continuously.

摘要： The present invention provides a battery-driven electronic device for which a long time use of the battery can be achieved and mobile communications equipment such as a portable telephone. Even if the time at which the output voltage of a battery 201 becomes below the supply voltage required by a load 206 including a power amplifier for wireless communications comes earlier than a conventional lithium ion battery because of its discharge characteristics that the battery voltage change ratio is 0.25 or more, a step-up and -down converter 200 operates as follows. When the output voltage of the battery is higher than the supply voltage required by the load, the voltage is set to a predetermined supply voltage by the step-down operation mode. When the output voltage of the battery is decreased and becomes lower than the supply voltage required by the load, the voltage is set to a predetermined supply voltage by the step-up operation mode. Thus, even for a battery employing a new material having a high energy density, a long term use of the battery can be achieved.

摘要： In a DC-DC converter equipped with an operation mode (standby operation mode) which is only for reducing consumption power in a light load state such as at the time of a start-up, there is an output power dive detecting circuit disposed which outputs a result of a comparison of an upper limit output voltage E1, which is higher a predetermined voltage than a target output voltage E0, with an output DC voltage Vo. The DC-DC converter does not enter the standby operation mode when the output DC voltage Vo is higher than the upper limit output voltage E1, which greatly improves a response speed at which the output DC voltage Vo efficiently reaches the target output voltage E0.

摘要： The power supply unit has a sample-and-hold circuit that samples a voltage supplied from a power source to a load according to a sample timing signal and holds the voltage as an output set value for the DC/DC converter. The unit supplies a load with an output from the DC/DC converter controlled so that an output voltage of a power source becomes an output set value of the DC/DC converter when the voltage of the power source drops. Since a voltage corresponding to the voltage of the power source before the voltage drop is set to the output set value of the DC/DC converter, a stable power supply unit is obtained in which the difference is always small between the voltage of the power source in normal times and the output voltage from the DC/DC converter when the voltage of the power source temporarily fluctuates.

摘要： A DC-DC converter includes a control circuit which can change the target voltage of the reference voltage source. At the start-up of the DC-DC converter, the PWM control circuit controls so that the first switching element gradually increases the on-off ratio from a minimum on-off ratio; that the second switching element is placed in the OFF state, and that the target voltage is set higher than the normal operating voltage. When the start-up operation is completed, the PWM control circuit controls so that the second switching element starts to turn on and off, and that the target voltage is returned to the normal operating voltage.

摘要： In a bidirectional power supply device, a DC-DC converter is connected such that the longer an ON time of the first switch becomes, the higher a voltage of a second positive terminal and a second negative terminal becomes. When stopping the supply of power from a first positive terminal and a first negative terminal to a second positive terminal and a second negative terminal, a control circuit turns OFF a third switch, and then operates a switching signal generation circuit so that the ON time of the first switch becomes a maximum. The switching signal generation circuit is operated so that the ON time of the first switch becomes a maximum with the third switch turned OFF in start-up when supplying power from the second positive terminal and the second negative terminal to the first positive terminal and the first negative terminal.
