ELECTRICAL CHARACTERISTICS
Electrical characteristics apply over the full operating range of input voltage, output power and baseplate temperature, unless otherwise
specified. All temperatures refer to the operating temperature at the center of the baseplate. Performance specifications are based on the
ENMod system as shown in Figure 1a.
