基于CPCI的嵌入式系统的电源设计

Power supply design of embedded system based on CPCI

介绍一种基于CPCI的嵌入式系统的电源设计方案。分析系统的功耗需求后,介绍系统使用的3种新型电源器件。随后,重点讨论LDO型电源器件LT3501。详细阐述配置该电源电路多项重要参数的方法。该电源系统已在某嵌入式系统中得到成功运用,并且具有一定的通用性,可应用于类似的嵌入式系统中。

This paper introduces a power supply design plan of an embedded system which is based on CPCI. After analyzing the system＇s power demand, three novel power supply chips are introduced. Subsequently,a new LDO chip LT3501 is discussed as the emphasis.And how to configure the important parameters of this power supply circuit is explained in detail.This power supply system has been successfully used in an embedded system.Its universality makes it can be applied to similar embedded system.
