| Abstract: | The separate components of the voltage regulator block TL430 and the power transistor TIP127 are used to constitute wide range of input voltage and output voltage of ＋ 5 V DC-DC DC regulated power supply. The MSP430F149 MCU is used to realize the output current,leakage current,output voltage and power measurement. It can automatically cut off the output voltage protection according to the leakage current. It has the characteristics of high measuring precision and sensitive leakage protection. |
