| Abstract: | Buck switching mode power supply is widely used in modern electronic equipment, In this paper, Design of Buck type switching power supply using LM3150 as the power chip is introduced by studying the principle of Buck converter. Optimization of efficiency, cost, size and the switching frequency is achieved;choose the peripheral component suitable with the help of WEBENCH power supply design tool. The simulation shows that the power has good stability, high conversion efficiency, and can be widely used in portable devices. |
