The invention relates to the technical field of wireless charging, and provides a highly-integrated linear charging voltage stabilizing circuit and an application thereof. The highly-integrated linearcharging voltage stabilizing circuit mainly comprises a rectifier module, a linear charging voltage stabilizing module and a power supply self-switching module. The linear charging voltage stabilizing module is configured to perform a linear charging mode for a battery load according to a first instruction input by a user and perform a linear voltage-stabilized output mode for a non-battery loadaccording to a second instruction input by the user. The power supply self-switching module is configured to make the highly-integrated linear charging voltage stabilizing circuit switched flexibly between wired and wireless power supply modes. Compared with the prior art, the highly-integrated linear charging voltage stabilizing circuit provided by the invention achieves a linear charging function or a linear voltage-stabilized output function with fewer requirements on external components. When the circuit is applied to a low-power equipment charging product, the volume or size of the charging product can be greatly reduced, and the cost of the charging equipment can be reduced. The circuit has a wider application prospect.
Description
technical field [0001] The present invention relates to the technical field of wireless charging in the field of integrated circuits, and more specifically, to a highly integrated linear charging voltage stabilizing circuit, a charging circuit including the circuit for low-power equipment, and applications of the charging circuit. Background technique [0002] The wireless charging technology based on WPC (Wireless Power Consortium) or Qi protocol is more mature than other technologies, so it is more widely used. It is a method based on electromagnetic induction, which induces energy from the primary coil to the secondary coil, so as to achieve the function of wireless energy transmission. [0003] At present, WPC defines the basic power specification (BPP, Baseline Power Profile), which is mainly used for low-power devices below 5W. And the Extended Power Profile (EPP, Extended Power Profile), which is mainly used for medium power devices within 15W. Compared with EPP equ...
