id="article"><div> <div>全球领先的充电体验，源于小米手机首款标配纳微GaNFast氮化镓充电器</div> <div> </div> <div>爱尔兰都柏林（PRWeb）：纳微半导体15日宣布，其氮化镓（GaN）功率芯片已正式被小米55W氮化镓充电器采用（型号MDY-12-EQ），该充电器在小米11手机智能手机海外上市时，随机附赠。小米11是全球首款采用高通骁龙 888芯片的5G智能手机，拥有6.81英寸康宁新一代大猩猩玻璃的 AMOLED屏幕和1440p分辨率，以及4600 毫安时的电池。通过使用配备纳微GaNFast氮化镓功率芯片的55W氮化镓充电器，小米11仅需要45分钟就可以完成0%到100％的充电，充电时间是竞争对手旗舰手机的一半，而且体积非常紧凑，仅为传统硅基充电器的一半大小。</div> <div> </div> <div style="text-align: center;"><img src="http://www.casmita.com/file/upload/202103/18/150556261.jpg" width="650" height="462" alt="" /></div> <div> </div> <div> </div> <div>氮化镓（GaN）是第三代半导体技术，其运行速度比旧的慢速硅（Si）快20倍，并且可以以三分之一的体积和重量，实现高达三倍的功率或充电速度。纳微GaNFast氮化镓功率芯片集成了GaN器件，驱动器以及保护和控制功能，可提供最简单，最小，最快的电源解决方案，如今甚至是更高的电源性能。小米55W氮化镓充电器在高频准谐振（HQFR）反激拓扑上使用纳微NV6115 GaNFast氮化镓功率芯片，并采用安森美NCP1342控制器以200kHz的频率运行，可实现超薄的平面变压器设计以及更小的EMI滤波器和输出电容器。</div> <div> </div> <div>小米集团合伙人高级副总裁、国际部总裁周受资先生在小米11全球发布会上表示：“ 55W 氮化镓充电器最重要的一点，是能够为您的许多电子设备进行充电，包括笔记本电脑，游戏机和智能手机等。我们相信这才是真正世界一流的充电体验。”</div> <div> </div> <div style="text-align: center;"><img src="http://www.casmita.com/file/upload/202103/18/150610651.jpg" width="650" height="462" alt="" /></div> <div> </div> <div>纳微半导体首席执行官兼联合创始人Gene SHERIDAN表示：“继2020年2月在小米10发布会上，纳微GaNFast氮化镓功率芯片首次被小米65W氮化镓充电器采用，氮化镓开始进入人们视线，到2020年10月在小米技术与投资日上，纳微半导体吉祥物“小氮小镓”首秀，引发行业轰动。到今天，我们非常激动与小米11一起，将氮化镓技术推向全球市场。小米11标配的55W纳微GaNFast氮化镓充电器海外版拥有欧标的2-pin AC，这是标志着主流一线智能手机厂商已开始采用氮化镓技术，也标志着行业开始淘汰旧的低速硅芯片。”</div> </div></div> </div> <div class="keytags"> <strong>标签：</strong> <a href="http://www.casmita.com/news/search.php?kw=%E5%B0%8F%E7%B1%B311"
