Datasheet里有以下参数:
Junction to thermal pad resistance θJP is 10.24°C/W.
Junction to ambient thermal resistance θJA is 52.06°C/W.
请教θJC(Junction to Case(Top)thermal resistance)的值是多少?
已知TPS51200表面实际的温度,使用θJC计算Tj的值。
谢谢!

谢谢您!
θJA = 55.6℃/W
θJC = 84.6℃/W
请问θJC 比 θJA 大这么多?是在什么情况下得出的数值呢?一般情况下,θJA 会比 θJC大一些吧?
