2、PL2700 USB限流IC设计PCB建议:

PCB Layout RecommendationsWhenlayingouttheprintedcircuitboard,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
