This series is a 3-in-1 fast charging controller that integrates a 32-bit main control MCU, fast charging protocol communication circuit, and a high-efficiency DCDC power conversion unit on a single chip , completely breaking the multi-chip combination architecture in traditional solutions, highly integrating the three core functions of control operation, protocol negotiation, and power conversion on a single chip, achieving multiple advantages of peripheral simplification, performance optimization, cost control, and high development efficiency at the system level. At the same time, relying on the programmable core and open development ecosystem, it fully supports deeply customized overall software and hardware solutions and can be flexibly adapted to diverse application scenarios.
