摘要
便携式产品的功耗要求决定了处理器的多电压供电模式。文章首先对双输出电源芯片LTC3407EDD-2进行了介绍,其次对芯片的内部结构进行了描述,详细讲解了其各个引脚的功能,最后对主要的元件参数设置和电路连接进行了说明,并给出了实际应用的电路图。实践证明,该芯片紧凑、高效,使用方便。
Multi-voltage supply mode of processor is decided by the power need of portable device. In this article, the dual-output IC LTC3407EDD-2 is introduced firsty. Then its internal structure is described and functions of its each pins are explained in detail. At last, main parameters and circuit connection of the IC are illuminated and the circuit diagram is given. Practice pro^es that the 1C is compact efficient and easily used.
