Using single-chip MSP430F449, a Boost-type switching mode power supply is designed based on PWM con-troller TL494. 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 cur-rent values. In this paper, the design and parameters calculation procedure are given in detail and the design is testified by experiment.
