Southchip announced the launch of a new GaN dual-C port fast charging solution - AC200, which has the advantages of low cost, high efficiency, and good EMI performance. Compared with the traditional dual-C port solution, DC/DC can be omitted, and the efficiency can be increased by more than 3%~5%. Since there is no additional DC/DC output, the EMI characteristics are more friendly. It has obvious advantages for 40W~65W dual-port adapters and solves the temperature problem. Increase the bottleneck point, save the glue-filling process in mass production, and save the output common mode inductor.
The solution adopts a full set of Southchip solutions to realize 2T2C power conversion and uses a packaged GaN QR FLYBACK converter SC3056 + packaged SR controller SC3510 + protocol chip SC2151A, which has the advantages of low cost, high efficiency, and good EMI performance.
Input: 90Vac ~ 264Vac
Output: 2 C ports support blind insertion, intelligent power distribution, compatible with FC, AFC, FCP, PD3.0, and PPS mainstream fast charging protocols, with 3.3-21V / 3A PPS voltage gear, the maximum output power of a single port is 65W (20V / 3.25A).
This solution maintains good portability while focusing on 45W+18W dual-port fast charging, which is more suitable for Apple users with multiple devices. Of course, it can also meet the fast charging needs of Huawei, Xiaomi, and other brand devices.
- Both ports support blind insertion 65W
- Two ports load at the same time, 45W+18W max
- Supporting agreement
Full-load efficiency: The dual-transformer parallel architecture has significantly improved compared to the traditional two-stage series architecture, bringing customers a more efficient charging experience.
