Figure 1 — Specified thermal operating area
1. The BCM in a VIA package is cooled through 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 internal operating temperature does not exceed 125°C.
