In this paper,a design about a program switching mode power supply of an oil logging tool is introduced.It includes tentative design,circuit design and so on.Based on actual requirement,the method of PFM resolves a wide range of DC output.The method of PWM improves the efficiency and the stability.In actual test,it can work a long time in the environment of 150℃.So the method of the design is feasible.
