Efficiency vs Output Current

Note A:

All data listed in the above graphs has been developed from actual products tested at 25°C. This data is considered typical data for the DC/DC Converter.

Note B:

SOA curves represent operating conditions at which the temperature of the metal case is at or below the maximum specified 100°C
