摘　　要：随着设备的集成技术和嵌入式技术的高速发展,低压大工作电流和安全可靠的电源系统已成为市场需求。传统的一步式电源系统很难达到这些要求,嵌入式系统二步转换式电源系统的设计是解决这一问题的理想方案。通过对美国L inear T echno logy公司生产的LTC 1628和LT 1121的介绍,论述了嵌入式系统电源结构的组成、原理和设计方法。Along with the high speed of development of integration technique and embedded technique, a safe and trustiness with low--voltage, high electric current power system is required by the market. The traditional one-step power system is difficult to match these requirements. The design of two-step embedded system power system is the perfect solution. In this article, it describes the constitution, the principle and the design way of the power system＇s structure of embedded system by the introduction of the American Linear Technology＇s products LTC1628 and LTC21.
