移动设备


现今的智能手机和平板电脑具有惊人的处理能力(四核、千兆赫兹处理器)、存储器以及创新软件和无处不在的通信能力,在移动环境下提供信息和娱乐。

平板电脑采用与智能手机几乎相同的半导体技术,主要区别在于屏幕大。平板电脑的电池容量通常也比较大,通常采用功能更强的处理器。

应用


电源管理

智能手机和平板电脑的功能不断扩展,新款产品通常会采用性能更高的处理器、更大的存储容量以及更多的附加功能。然而,电池体积不能增大,所以高效电源管理IC (PMIC)日益重要。许多移动产品中,PMIC不能提供全部必要的电源电压,还需要独立的稳压器。毋庸置疑,空间是无价之宝。设计用于当今移动设备的IC都要求提供极小的方案尺寸。

Maxim业界领先、高度集成的PMIC和电源SoC是智能手机和平板电脑的理想选择。关于Maxim适用于智能手机和平板电脑供电的最新PMIC技术,请联系Maxim销售代表

Maxim也提供适用于移动应用的小尺寸开关稳压器和LDO。
