High Current 40V LED Driver with Switch Dimming
1.3 Electrical Parameters
Except as noted, test conditions for the following specifications are T_amb = 25°C typical and V _IN = 12V unless
otherwise noted.
Production testing of the chip is performed at 25°C unless otherwise stated. Functional operation of the chip and
specified parameters at other temperatures are guaranteed by design, characterization, and process control.
