| Abstract: | Designs the AC-DC circuit module based on the switching power supply chip LM5118. The MSP430F16S MCU is used to monitor output voltage and output current. The design makes the output voltage and current basically stable, through the double closed loop control of voltage feedback and current feedback, which achieves output 36V and output 2A obtained. The system has the function of overload protection and display of real-time value, and the efficiency of the circuit can reach up to 96%. |
