— Specified thermal operating area
1. The BCM in a VIA package is cooled through the bottom case (bottom housing).
2. The thermal rating is based on typical measured device efficiency.
3. The case temperature in the graph is the measured temperature of the bottom housing, such that the internal operating temperature
does not exceed 125°C.
