Embodiment Construction

[0038] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Preferred embodiments of the application are shown in the accompanying drawings. However, the present application can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the application more thorough and comprehensive.

[0039] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention relates to a power supply equipment awakening circuit. The power supply equipment awakening circuit comprises a power consumption control circuit and an awakening circuit, wherein the power consumption control circuit is connected with the awakening circuit; the power consumption control circuit comprises a voltage regulation module and a protection circuit; the voltage regulation module is electrically connected with the protection circuit; the voltage regulation module regulates voltage output to the protection circuit according to a dormancy control signal; the protection circuit judges whether to trigger over-discharge protection or not according to the input voltage; and the awakening circuit comprises a first switching device, and outputs an awakening control signal tothe protection circuit based on the operation of the first switching device by a user so as to enable the protection circuit to stop triggering over-discharge protection. On one hand, the power consumption of a product can be reduced, and on the other hand, the product in a low-power-consumption state can be awakened.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a wake-up circuit for power supply equipment. Background technique [0002] At present, the standby current that common power supply technologies in the industry can achieve is usually around 200 microamperes, and the low-end power supply products even exceed 2 milliamperes. The power is controlled at no more than 30%, and after being transported to the destination, it is recharged before sale. Due to the need to control the power to no more than 30% during transportation, the requirements for the standby current of power supply products are more stringent. [0003] The current energy storage devices such as power supply products only reduce the standby current at the back end, which will lead to an incomplete reduction. How to reduce the standby current of power supply products more thoroughly is an important topic of concern in this paper. At the same time, how to wake...
