In this paper, the authors present the overall design of switching power supply control based on the ARM processor, the main circuit is given in a typical single-ended fly back circuit pattern, The basic idea of the power switch design is given, At the same time, The basic principle of power switching transformer design is also given, the control circuit uses the S3C2440 core chip, combined with the output sampling, solve the control MOS switch tube on and off signal PWM control. Switching power supply output voltage is 0.1V/level adjustment, adjust the dynamic range increases.
