1、PL2700 usb限流开关IC 典型电路：外围简单，一个电阻，2稍僚敉视个贴片电容。PL2700，可调限流0.5A-2A，带输出短路保护PL2702，可调限流1A-3A，带输出短路保护。视褂撼室酸频内容是：PL2700进行输出短路保护测试。
2、PL2700 USB限流IC设计PCB建议：PCB Layout RecommendationsWhenlayingouttheprintedcircuitboard荑樊综鲶,thefollowing checking should be used to ensureproper operation of the PL2700. Check thefollowing in yourlayout: Doesthe(+)platesofCINconnecttoVINascloselyaspossible.Thiscapacitorprovidesthe AC current to the internal powerMOSFETs. Keepthe(-)platesofCINandCOUTascloseas possible
