Dialog的电源管理芯片组可实现三星的自适应快速充电紧凑型墙适配器，以便在课堂上充电时间提供市场领先的效率
London, United Kingdom–2015年12月02日–Dialog Semiconductor plc（Xetra：DLG), a provider of highly integrated power management, AC/DC power conversion, solid state lighting (SSL) and Bluetooth® Smart technology, today announced that one of its advanced power management chipsets is at the heart of Samsung’s latest Adaptive Fast Charging (AFC) AC/DC wall adapter. The custom chipset incorporates Samsung’s proprietary AFC technology. The design win builds upon Dialog’s estimated 70% market share of the rapid charging adapter market for smartphones, tablet and other mobile devices.
The small, lightweight Samsung adapter has a USB output connector and is designed for use with the Galaxy S6, Galaxy Note 4 and later models of the Galaxy S and Galaxy Note series smartphones. It typically charges the batteries from 0 to 50% in 30 minutes. The power supply can also charge other devices over a micro-USB cable, delivering 5 volts at up to 2 amps.
Analyst IDC predicts smartphone shipments will reach1.44 billion units in 2015在2019年，增长至19亿单位。根据分析师，三星举行了一个市场领先的21.4％的份额智能手机市场在季度2015年第295季度。智能手机通常与AC / DC适配器一起出售，但也有一个越来越多的独立适配器市场，可用于通过USB收取各种设备。
“Dialog’s rapid charge solutions have continued to gain traction in the mobile market, with our latest Samsung success solidifying Dialog’s leadership position,” said Davin Lee, Senior Vice President of the Power Conversion Business Group for Dialog Semiconductor. “Our solutions offer best in class efficiency, total solution size, performance and cost while delivering valuable competitive advantages to an innovation leader such as Samsung.”
Three complementary Dialog power management devices are used in the adapter. TheIW1780primary-side digital controller incorporates Dialog’s patentedSmartDefender™先进的HICCUP技术，防止在充电器电缆或连接器中发生软短路时过度的热积聚和损坏。这导致更安全，更可靠的快速充电。IW627二级侧监管机与IW1780AC / DC控制器以确定充电循环中的每个点处的最佳电压/电流。最后，iW671同步整流器用MOSFET替换传统设计的次级侧肖特基二极管，使用专有的自适应关闭技术将效率提升到超过88％，减少适配器内产生的热量，并使得要使用较小的情况。
