Article Source：China National Intellectual Property Administration | Author：Financial Sector | Issuing Time：2024.04.10
On April 4, 2024, the financial sector reported that, according to the announcement of the China National Intellectual Property Administration, Shanghai Awinic Electronic Technology Co., Ltd. has obtained a patent entitled "a boost circuit and charger", with the authorization announcement number of CN109639110B and the application date of December 2018.



The patent abstract shows that the present invention provides a boost circuit, comprising a high-voltage boost unit and a switching unit; The switch unit is connected to the high-voltage boosting unit, wherein the control end of the switch unit is connected to the first signal output end of the high-voltage boosting unit; When the high-voltage boosting unit determines that the output voltage of its output terminal is less than the threshold voltage, it outputs a first signal; When the control end of the switching unit receives the first signal, it will turn off itself to ensure the connection and disconnection between the high-voltage boosting unit and the load circuit. The present invention discloses a boost circuit that solves the problem of burning out the high-voltage boost unit when a load circuit is short circuited by adding a switch unit. This enables the boost circuit disclosed in the present embodiment to automatically cut off power when a load circuit is short circuited, thereby increasing the safety of the boost circuit; Moreover, due to the simple structure of the boost circuit disclosed in the present invention, it is convenient for widespread application.
