iW676 数字同步整流器可与瑞萨电子的多个初级侧控制器配合使用，为智能手机和媒体平板电脑高功率密度、低 BOM 成本的适配器（包括 RapidCharge™ 和直接充电应用）提供高效解决方案。

iW676 采用专有的数字自适应关断控制技术，用 MOSFET 取代次级侧并联肖特基二极管，以实现高功率密度和低成本。 iW676 比其替代的二极管更高效，也比传统的同步整流器更高效。

iW676 经过优化，可在高达 12V 的应用中实现最低的 BOM 成本，并可直接充电至 3V。 该器件还可结合瑞萨电子独特的有源电压定位（AVP）控制，实现整个旅行适配器的超快速动态负载响应（DLR）和低至 20mW 的空载功耗，无需添加引脚或外部组件。

iW676 提供 DiaSIM™ 仿真模型。 更多信息和下载方式，请访问 DiaSIM 页面。
