[0002] With increasing demands for environmental protection and energy conservation, battery usage and stepped operating voltage designs have become widespread. However, battery voltage drops when outputting high current at low temperatures, necessitating a boost voltage boosting process. But boost circuits introduce drawbacks such as increased standby power consumption and reduced efficiency. This invention leverages the characteristics and requirements of stepped voltage design in low-power devices to optimize the battery's output circuit, thereby achieving low-power, high-efficiency regulated output and overcoming the shortcomings of conventional boost circuits. Summary of the Invention

Diode 2, the positive terminal of diode 2 is connected to pin 2 of the boost chip; The load has its pin 1 connected to the negative terminals of diode 1 and diode 2, its pin 3 connected to pin 4 of the boost chip, and its pin 2, the boost chip pin 3, and the negative terminal of the battery grounded.

[0004] A battery output circuit with uninterrupted power supply, low power consumption, high efficiency boost voltage regulation according to an embodiment of the present invention has the following beneficial effects: 1. When the load is operating normally and the boost chip is turned on, the input voltage of the load will not decrease as the operating current increases. This effectively solves the defect of battery voltage fluctuating with changes in output current, and the effect is even more significant at low temperatures.

[0005] 2. The boost converter chip is not always on during system operation, effectively improving its lifespan. When the boost converter chip is off, system power consumption decreases, improving efficiency and extending battery life.

[0006] 3. During the instantaneous switching between the off and on states of the boost chip, diodes one and two conduct alternately, achieving zero time interval.

[0007] It should be understood that both the foregoing general description and the following detailed description are exemplary and intended to provide further illustration of the claimed technology. Attached Figure Description

[0008] Figure 1 This is a circuit diagram of a battery output circuit that provides uninterrupted low power consumption, high efficiency boost voltage regulation, according to an embodiment of the present invention. Detailed Implementation

[0009] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0010] First, combine Figure 1 This invention describes a battery output circuit with uninterrupted power supply, low power consumption, high efficiency boost voltage regulation, according to an embodiment of the present invention. It is used for power output from battery B1 and has a wide range of applications.

[0011] like Figure 1 As shown, an embodiment of the present invention provides a battery output circuit with uninterrupted power supply, low power consumption, high efficiency boost voltage regulation, comprising a battery B1, diode D1, boost chip U1, diode D2, and load L1.

[0012] Specifically, such as Figure 1 As shown, the anode of diode D1 is connected to the anode of battery B1; pin 1 of boost converter U1 is connected to the anode of battery B1; the anode of diode D2 is connected to pin 2 of boost converter U1; pin 1 of load L1 is connected to the cathodes of diodes D1 and D2, pin 3 of load L1 is connected to pin 4 of boost converter U1, and pin 2 of load L1, pin 3 of boost converter U1, and the cathode of battery B1 are grounded. With the cooperation of diodes D1 and D2, boost converter U1 can be freely switched on or off, maintaining a stable output voltage for battery B1 under high current output conditions.

[0013] Working principle: The load L1 adjusts the external input voltage through its pin 3 (GPIO). When the boost chip U1 is turned on, the high voltage input V2 is obtained, the diode D1 is cut off, and the low voltage input is isolated.

[0014] When the boost converter chip U1 is turned off, a low-voltage input V1 is obtained, diode D2 is cut off, and the high-voltage input is isolated.

[0015] In the system's workflow, load L1 only needs to control the boost chip U1 to continuously control its own operating state: normal mode or sleep mode. In sleep mode, boost chip U1 is turned off, the standby current decreases, and after boost chip U1 is turned off, the input voltage of load L1 decreases accordingly, and the standby current decreases further.

[0016] Above, refer to Figure 1A battery output circuit with uninterrupted power supply, low power consumption, high efficiency boost voltage regulation according to an embodiment of the present invention is described, which has the following beneficial effects: 1. When the load L1 is working normally, turning on the boost chip U1 will prevent the input voltage of the load L1 from decreasing as the operating current increases. This effectively solves the problem of the battery B1 voltage fluctuating with the output current, and the effect is even more significant at low temperatures.

[0017] 2. The boost converter chip U1 is not always on during system operation, effectively improving its lifespan. When the boost converter chip U1 is off, system power consumption decreases, efficiency is improved, and the lifespan of battery B1 is extended.

[0018] 3. When the boost chip U1 switches between off and on, diodes D1 and D2 conduct alternately, achieving zero time interval.
