摘　　要：将USB OTG技术集成到电源管理类集成电路中有它自己的一套设计难题.其中包括需要高性能电源管理系统来适应不断提高的系统复杂性、更高的功率预算和热限制。这些系统力求在长电池工作时间、与多种电源的兼容性、高功率密度、小尺寸和有效热管理之间实现最佳平衡。一种新的电源管理集成电路(PMIC)可高效地为这些系统供电,并以小得多的占板面积和比其他传统PMIC高得多的性能来提供USB OTG功能。Integrating Universal Serial Bus On- the-Go(USB OTG)technology into power management ICs has its own set of design difficulties.Among these are the demands for high performance power management systems to accommodate growing system complexity,higher power budgets and thermal constraints. These systems strive for an optimum balance between long battery runtime,compatibility with multiple power sources,high power density,small size and effective thermal management.A new power management integrated circuit (PMIC)is available to efficiently power these systems and also provide USB OTG functionality in a much smaller footprint and with much higher performance than other traditional PMIC.
