| Abstract: | The paper designed a single-ended flyback multi-output switching mode power supply based on TOP246Y chip,which has eight outputs and provides a reliable voltage for the motor servo system in the power board and control board. This paper mainly introduced the high-frequency transformer and chip peripheral circuit design. According to the requirements of the design, the circuit diagram, the calculation step of main parameter of transformer as well as the main 5 V output t voltage waveform were presentecl. Experiments show that the power can provide a stable DC output to meet the design target requirements in the case of input voltage fluctuations. |
