摘要
基于TinySwith系列芯片,详细介绍了一款定时计数单元供电的开关电源的设计方法,该电路在宽范围输入电压范围内,采用单端反激式拓扑电路,利用光藕反馈和脉冲宽度调制技术实现电压稳定输出。
Based on Tinyswitch series chip, the paper introduced a design method of switching mode power supply particularly, which is used for power supply of a timing unit. The supply adopted single - end flyback topology, by using photoelectricity copling feedback and PWM technology, it can realize the output voltage steady.
