输入参数:R1 (ohm); R2(ohm); C(F)文章源自公式库网-https://www.gongshiku.com/html/201910/dianzidianlu555dingshidianlushuzhizaixianyijianshengchengjisuanqi.html

输出参数:占空比(%), 高电平时间(s),低电平时间(s), 频率(Hz)文章源自公式库网-https://www.gongshiku.com/html/201910/dianzidianlu555dingshidianlushuzhizaixianyijianshengchengjisuanqi.html

计算公式:
TH (高电平时间s) = 0.693 (R1 + R2) C
TL (低电平时间s) = 0.693 R2 C
Frequency(输出频率) = 1.44 / ((R1 + R2 + R2) C)
DCP(占空比%) = (T(h) / (T(h) + T(l))) 100
