摘要
基于TOP204单片开关电源控制芯片,实现了精确的±15 V双路输出。根据TOP204的特性,给出了单端反激式开关电源的工程设计方法。结合真空镀膜电源检测系统供电要求及特点对其外围电路进行了分析和讨论,并在实验的基础上对该电路的性能进行了验证。
A kind of single-ended fly-back switching power supply based on TOP204 was designed with the two-channel accurate outputs of ±15 V. Its engineering design method was brought forward according to the character of TOP204, and its peripheral circuits were analyzed and discussed in terms of requirements and characteristics of power detection system. At last the performance of the power supply was verified through experiments.
