Overview:

The SW3566 is a highly integrated multi-fast-charging protocol dual-port charging SoC chip. It supports fast charging output from any port in C+C, C+A, or A+A configurations and features independent current limiting for each port. The chip integrates a 7A high-efficiency synchronous buck converter and supports various fast charging protocols such as PD3.1, QC, SCP, and UFCS, with a maximum output power of up to 140W. It incorporates CC/CV modes, dual-port management logic, and bus voltage detection. Additionally, it features a built-in Cortex-M0 CPU to meet customization requirements for fast charging protocols. With only a few external components, it can form a complete, high-performance multi-fast-charging dual-port charging solution.
