This paper presents a design for switch power, with the characteristics of mini-watt, wide-input （85-265VAC） , and high load capacity. As the core of fly-back DC / DC converter, the power applies Chip TOP254YN, a type of TOPS- witch-HX series of integrated switch power developed by PI Company of U. S. , and realizes the performance of wide-input voltage and output capability of stable voltage by taking advantage of the current PWM negative feedback control. The de- sign of the power, the producing and debugging process of a ＋5 V/10 W power sample are also described in the paper.
