Dialog’s power management chipset enables Samsung’s Adaptive Fast Charging compact wall adapter to deliver market-leading efficiency with best in class charging time
英国伦敦–December 02, 2015–雷竞技电竞平台Dialog半导体plc(XETRA:DLG公司)一家提供高度集成的电源管理、交直流电源转换、固态照明（SSL）和Bluetooth®智能技术的供应商今天宣布，其先进的电源管理芯片组之一是三星最新的自适应快速充电（AFC）交直流墙壁适配器的核心。定制芯片组采用了三星专有的AFC技术。Dialog在智能手机、平板电脑和其他移动设备的快速充电适配器市场占有70%的市场份额。
这款小巧轻便的三星适配器配有USB输出接口，专为Galaxy S6、Galaxy Note 4及更高型号的Galaxy S和Galaxy Note系列智能手机设计。它通常在30分钟内将电池从0%充电到50%。该电源还可以通过微型USB电缆为其他设备充电，提供5伏电压，最高可达2安培。
分析师IDC预测智能手机出货量将达到2015年14.4亿台, growing to 1.9 billion units by 2019. According to the analyst,Samsung held a market-leading 21.4% shareof the smartphone market in Q2/2015. Smartphones are often sold together with AC/DC adapters but there is also a growing market for standalone adapters that can be used to charge a variety of devices over USB.
“Dialog的快速充电解决方案继续在移动市场获得吸引力，三星的最新成功巩固了Dialog的领导地位，”Dialog Semiconductor电源转换业务组高级副总裁Davin Lee说。“我们的解决方案提供一流的效率、总体解决方案规模、性能和成本，同时为三星这样的创新领导者提供宝贵的竞争优势。”雷竞技电竞平台
适配器中使用了三个互补的对话电源管理设备。这个iW1780一次侧数字控制器采用Dialog的专利技术SmartDefender™advanced hiccup technology, preventing excessive heat build-up and damage when soft short circuits occur in the charger cable or connectors. This results in safer, more reliable rapid charging. The iW627 secondary-side regulator communicates with theiW1780AC/DC controller to determine the optimum voltage/current at every point in the charging cycle. Finally, theiW671型synchronous rectifier replaces the secondary-side Schottky diode of a conventional design with a MOSFET and uses proprietary adaptive turn-off technology to boost efficiency to over 88%, reducing the heat generated within the adapter and enabling a smaller case to be used.
