TPS40210: 耦合电感计算公式

Part Number: TPS40210

请教TPS40210应用于SEPIC拓扑时,使用耦合电感,电感值的准确计算方法和公式是怎样的?我尝试过
Power Stage Designer 5、
WEBENCH® POWER DESIGNER、TPS4021x DC/DC Coupled Inductor SEPIC Controller Design Tool 这些设计工具,得出的结论都不一样,同时都看不出是怎样的计算公式。还有TI官网查到的一些关于SEPIC设计的应用手册,给出的公式也不一样,而且与上面三种设计工具的结果也无法对应。很困惑,不知道该怎么计算,哪种工具或者文献给出的结果或方法才是准确无误的?请帮忙解答下,多谢!
