    • If an input voltage to an output control device is above a lower limit value, the output control device operates in a constant voltage control mode for maintaining an output voltage at a substantially constant voltage. If the input voltage of the output control device falls below the lower limit value, the output voltage is controlled to be lower than the constant voltage in the constant voltage control mode, and the output control device operates in a lower limit value sustaining mode for maintaining the input voltage at the lower limit value. Then, the output control device shifts to a current increasing mode in which the output current rises as the output voltage falls.
    • 如果对输出控制装置的输入电压高于下限值,则输出控制装置以恒定电压控制模式工作,以将输出电压保持在基本恒定的电压。 如果输出控制装置的输入电压低于下限值,则输出电压被控制为低于恒定电压控制模式中的恒定电压,并且输出控制装置在维持下限值维持模式下工作 输入电压在下限值。 然后,输出控制装置转移到输出电流随着输出电压下降而上升的电流增加模式。

    • An FET 21 is connected in parallel to a series circuit of a switching device 13 and an inductor 12 between an input terminal 11a and an output terminal 11b, wherein an output voltage Vout is dropped only by an operation of the switching device 13; the FET 21 is turned on by a driving circuit 22 when the switching device 13 sustains an on duty factor of 100% so that a series resistance of the switching device 13 and the inductor 12 is connected in parallel to an on resistance of the FET 21, thereby increasing a supply current and extending a period during which an output voltage provided to the output terminal 11b is sustained at a predetermined level. Therefore, a power circuit capable of extending an operating time of a battery-operated power supply, a method for driving same, and further an electronic module implementing same can be obtained.

    • The present invention provides a switching circuit and an electronic switching component having a switching semiconductor device to perform switching between a conducting state and a non-conducting state of a conducting path to thereby reduce the power loss thereof and a control method thereof. In the present invention, at least two FETs 11 and 12, wherein the FET 11 has a faster switching time and the FET 12 has a lower ON resistance. Active terminals (drains and sources) of the FETs 11 and 12 are connected to each other in parallel. By employing these FETs 11 and 12, the conversion between an ON-state and an OFF-state of the conducting path is performed. In converting from the non-conducting state to the conducting state, the control circuit 13 first turns on the FET 11 and then turns on the FET 12 when if a voltage between terminals of the FET 11 reaches around a saturation value thereof. In converting from the conducting state to the non-conducting state, the control circuit 13 first turns off the FET 12 and then turns off the FET 11 when if a voltage between terminals of the FET 11 reaches around a saturation value thereof.
    • 本发明提供一种开关电路和具有开关半导体器件的电子开关元件,以进行导通路径的导通状态和非导通状态之间的切换,从而降低其功率损耗及其控制方法。 在本发明中,至少两个FET 11和12,其中FET 11具有更快的开关时间,并且FET 12具有较低的导通电阻。 FET 11和12的有源端子(漏极和源极)并联连接。 通过采用这些FET11,12,进行导通路径的导通状态和截止状态之间的转换。 在从非导通状态转换为导通状态时,如果FET 11的端子之间的电压达到其饱和值,则控制电路13首先接通FET 11,然后导通FET 12。 在从导通状态转换为非导通状态时,如果FET 11的端子之间的电压达到其饱和值,则控制电路13首先关断FET 12,然后关断FET 11。
