*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.
Absolute Maximum Ratings Unless specifically noted, TA is 25°C
