[0002] Wireless charging technology has become an important charging method for modern portable electronic devices and is widely used in smartphones, electric vehicles and wearable devices. The wireless charging receiver control chip is the core component of this technology, responsible for managing the charging process and ensuring its efficiency and safety. The basic architecture of the chip usually includes several key parts: receiving coil, rectifier circuit, control unit, energy storage unit and protection circuit. The market demand for wireless charging receiver control chips continues to grow, especially in the fields of smartphones and electric vehicles. In the future, with the popularization of smart homes and the Internet of Things, wireless charging technology will usher in more application scenarios, driving the receiver control chip to develop in the direction of higher efficiency, smaller size and lower cost. In summary, the architecture of the wireless charging receiver control chip is not only a product of technological development, but also a key factor in promoting the widespread application of wireless charging.

[0003] When designing a wireless charging receiver control chip, multiple factors need to be considered, including energy conversion efficiency, compatibility, size, and cost. High-efficiency energy conversion can reduce energy loss and increase charging speed, while compatibility with multiple wireless charging standards can meet the needs of different devices. With the advancement of technology, the size of chips has gradually decreased and the integration has continued to increase to adapt to the space limitations of portable devices.
