RapidCharge™ Dedicated Charging Port Controller
The iW632 is a RapidCharge™ Dedicated Charging Port (DCP) controller for Qualcomm®快速Chargetm 2.0（QC2.0）技术，可选的三星自适应快速充电（AFC）和分频器模式USB接口。它允许快速充电QC2.0或分频器模式的移动设备（MDS），它会自动识别QC2.0，AFC和分频器模式协议。IW632驻留在电源适配器的USB端口上，并允许适配器配置为5V，9V或12V的多电平输出，具体取决于MD所要求的电压。
It can be used in DC/DC power converter systems to achieve smooth voltage transition and low no-load power consumption. The iW632 implements three output pins for output feedback ratio change, output over-voltage, and fault and reset signals. In addition, iW632 also implements proprietary D+/D- over-voltage protection (OVP) and proprietary D- impedance detection to address soft short issues in the output cables and connectors that can be caused by such things as a poor or loose connection between the cable connector and the socket, contamination in the USB connector, or a worn-out cable, and provides protection against the damages.
