Note A:

Characteristic data has been developed from actual products tested at 25°C. This data is considered typical data for the Converter.

Note B:

SOA curves represent the conditions at which internal components are at or below the manufacturer’s maximum operating temperatures. Derating limits apply to

modules soldered directly to a 4-layer PCB with 1 oz. copper.
