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