USB PD和快速充电器

USB PD和快速充电器

USB PD/QC3.0等快速充电器协议可大幅缩短手机的充电时间，从过夜充电缩至不到30分钟。对用户而言，充电更为快捷，几乎可以不间断使用移动设备。

USB PD必定成为移动设备充电的新标准。USB PD的功率能力高达100 W，这样用户能将一个充电器同时用于手机、平板电脑和笔记本电脑。

PowiGaN™ 是Power Integrations自行研发的氮化镓（GaN）技术。在PI高度集成的离线反激式开关IC中，PowiGaN开关替代初级侧的传统硅晶体管，从而降低开关损耗，

和硅器件相比，PowiGaN产品可实现体积更小，重量更轻，效率更高的充电器，适配器和敞开式电源。基于PowiGaN的IC在整个负载范围内的效率高达95％，在封闭式适配器不需散热片就可实现高达100W输出功率。
