摘　　要：为了提高移动电源的实用性,使移动电源具有定时掉电和手动调压功能。阐述了STC89C52控制光耦开关定时通断的原理,讨论了升压芯片XL6009在功耗、稳压的方面的特点。采用STC89C52实现对移动电源的定时控制,通过芯片XL6009实现移动电源输出电压可调。本系统最终实现移动电源定时掉电和手动调压的功能。In order to improve the practicability of mobile power supply that is the mobile power supply has the function of timing power drop and manual adjustment. This paper describes the principle of STC89C52 control of the time-lapse of the optical coupling switch, and discusses the characteristics of the lifting chip XL6009 in power consumption and stabilization. The STC89C52 is adopted to realize the timing control of the mobile power supply, and the output voltage of the mobile power supply can be adjusted by the chip XL6009. The system finally realizes the function of the mobile power to drop the power and manually adjust the voltage.
