摘要
利用单片机MSP430F449，以电压型PWM控制器TIA94为核心，设计了一种Boost型稳压输出开关电源。该系统电路结构简单，直流输出电压可调范围为30-36V，效率高达90％，具有过流、过压保护并可实时显示输出电压与电流值。文中给出了详细设计思路和器件参数计算过程，并进行了实验验证。
Using single-chip MSP430F449, a Boost-type switching mode power supply is designed based on PWM controller TIA94. The circuit structure of this system is simple and with over-current, over-voltage protection. The DC output voltage ranges from 30 V to 36 V and the efficiency can be up to 90 %. Also this circuit can display output voltage and current values. In this paper, the design and parameters calculation procedure are given in detail and the design is testified by experiment.
