Safe Operating Area Curves (See Note B)
Power Dissipation vs Output Current
Ripple vs Output Current
Note A:
Characteristic data 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 internal components are at or below manufacturer’s maximum rated operating temperatures.
