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 in.
× 4 in. double-sided PCB with 1 oz. copper.
