摘要
在分析了升压型开关稳压电源工作原理的基础上,详细介绍了以Max8715芯片为核心搭建用于微型传感器的直流升压电路的过程,并解决了搭建过程中所遇到的电路带载能力差、效率与稳定度低、纹波大等问题,最后给出了电路性能的相关测试结果,结果表明该电路满足微传感器的应用要求。
This paper analyzed the working principle of DC boost-up switching power supply, then introduced the process of building up the boost circuit for the application of micro - sensor by using Max8715 chip in detail, and resolved the problems of poor load capacity, efficiency, stability and high ripple voltage. At last, it givesthe test results of the performance of this circuit, which shows that it fit for the requirements of the application of micro-sensor.
