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
