*Based on the thermal rating; the allowable maximum output power can be
up to 120% to 140% of this value. However, maximum output power may be
limited in such an application with low output voltage or short duty cycle.
The polarity value for current specifies a sink as "+," and a source as “,” referencing the IC.
