About the resistance of θjc and θja, I have read these two reply in the E2E, but I still confused about the θjc and θja
From the reply, you explain the difference of θjc top and θjc bottom and θjc bottom is the main thermal path, which can calculate like this θja = θJC(bottom) + θCB + θpcb-A. But from other thermal path, θja = θJC(top)+ θCA, how can I understand that θjc top (50 C/w) is still larger than θja (33 C/w) as the picture showed ? When OPA564-Q1 works, the temp of top case is larger than junction? This is really confuse me, Please help with this.
Thank you so much.
