力端子である。 Switching regulators are generally used for commercial power,
Conventionally, when connecting to a power supply source such as a battery to configure one power supply system, the switch is not installed in the main circuit as shown in Fig. There is a method of turning on and off the output of the switching regulator 1 by providing a switch 3 and turning the switch 3 on and off. In the figure, T 1 and T 2 are input terminals, and T 3 and T 4 are output terminals.

ド、１５は電解コンデンサである。 According to this method, the current capacity of the switch 3 that turns on and off the power supply to the control unit 2 is extremely small compared to the current capacity of the switch when the switch is inserted in the main circuit, so it has the advantage of being inexpensive. It is well known that there are many switching regulators available. However, among the various DC stabilization methods for switching regulators, the first one is the step-up chopper method.
As shown in FIG. 2, the switching regulator 4 has resistors 5 and 6 inserted on its output side for detecting the output power, and the voltage is fed back to the control section 8 of the switching element of the transistor 7 for control. Therefore, even if the switch 9 that turns on and off the power supply to the control section 8 is turned off and the switching operation of the transistor 5 is stopped, current will always flow through the resistors 5 and 6. FIG. 2 shows an example of a switching regulator in which the first switching regulator 4 of the step-up type chopper type described above and the second switching regulator 10 of another DC stabilization type are combined. Turn on the power supply to the control unit 8 of the first switching regulator 4 and the control unit 11 of the second switching regulator 10,
Turn off the switch 9 and connect the output terminal T 3 ,
Even if the output supplied to T4 is turned off, power will be consumed by the resistors 5 and 6 for detecting the output of the first switching regulator 4 as described above. 7 is a switching element such as a transistor, 13 is a coil, 14 is a diode, and 15 is an electrolytic capacitor.

力供給源１２がバツテリの場合には開閉器を
OFFにしていてもバツテリを短時間で使用不能
にするという欠点があつた。 In this way, the power supply to the control units 8 and 11 is
Even if the switch 9, which turns ON and OFF, is turned OFF, current flows through the detection resistor into the switching regulator, resulting in high power consumption, especially when the power supply source 12 is battery-powered.
The drawback was that even if it was turned off, the battery would become unusable in a short period of time.
本発明は上述の問題を解消し、開閉器のOFF

The present invention provides a switching regulator that significantly reduces power consumption during operation and significantly extends the life of a power supply device.

る。 Figure 3 shows a first switching regulator using a step-up chopper system, which is constructed by connecting a coil 13 in series with the main circuit and a switching element such as a transistor 7 in parallel, and a second switching regulator using another DC stabilization system. A switching regulator 10 is combined with a switching regulator 10, in which a switching element 16 is connected in series with the output detection resistors 5 and 6 of the first switching regulator, and the switching element 16
is configured to operate in conjunction with a switch 17 that turns on and off the power supply to the control units 8 and 11. Therefore, when the switches 17 of the control units 8 and 11 are OFF, the switching elements 16 are synchronously turned OFF.
The current flowing through the detection resistors 5 and 6 when the switching regulator stops operating can be reduced to zero.
