VL100 Type-C转换方案

VL100是一个高度集成的单芯片,适应于USB Type-C 转DisplayPort交替模式控制器的设备,比如:Type-C 影像适配器,Type-C TV/显示器/投影仪,和Type-C多功能扩展设备。

VL100集成了充电UFP功能,从而在可以执行DP ALT模式视频输出功能的同时,也能对外部设备进行PD电源检测。外部电源支持5V USB电源,5V DC直流,或从Type-C适配器直接取电
VL100会对Type-C source端连接PD主机的sink端的电源进行智能管理,支持电池充电模式。内置了sbu1 / sbu2开关可支持Type-C线缆翻转功能。符合VESA协会定义的DP ALT模式的Type-C规格也可以适用于USB2.0的广告牌。
