All data listed in the graphs below have been developed from actual products tested at 25
°C. This data is considered typical
data for the DC-DC Converter. SOA curves represent operating conditions at which internal components are at or below
manufacturer's maximum rated operating temperature. For Figure 3 Safe Operating Area, V
I = 48 V.
