I have reviewed the VIPER319XD datasheet and the Power Supply Design Tool, and I have a few questions about this IC:
The datasheet only provides RthJA (80°C/W) and does not specify the RthJB value. In another datasheet for the same package, I found RthJB listed as 10°C/W (without the bottom pad provision). How is this thermal resistance possible, considering that components with a bottom pad typically exhibit the same thermal characteristics? Could you please confirm the RthJB value?
In the Power Supply Design Tool, there is a mention of IC capacitive loss, but I’m not clear on what that entails. If the output inductance increases, does this loss also increase? Could you please provide more details on this?
