| Abstract: | A switch power supply is designed in this paper. The system consists of integrated PWM chip UC3842, MAX4080 and some other peripheral circuits. The switch power supply is controlled by MCU AT89S52 and has the function of ＇＋＇ and ＇-＇ 1V stepping range. The system can accomplish over current protection by AT89S52 and relay. At the same time, the output voltage and current can be displayed at the real time. Experiments show the designed circuit has a higher voltage regulation, load regulation and higher efficiency. |
