5 / 45 page ![]() # Pin Description 11 ILIM A pull-down resistor to GND selects the peak current limitation 12 DIM A PWM signal in this input pin implements the LED PWM current dimming. It is pulled-down by internal 2 µA current 13 LX Switching node 14 LX Switching node 15 BOOT Connect an external capacitor (100 nF typ.) between BOOT and LX pins. The gate charge required to drive the internal n-DMOS is recovered by an internal regulator during the off-time 16 GND Signal GND -- E.P. Exposed pad must be connected to GND plane 3.3 Maximum ratings Stressing the device above the rating listed in may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above those indicated in the operating sections of this specification is not implied. Exposure to absolute maximum rating conditions may affect device reliability. Table 2. Absolute maximum ratings Symbol Description Min. Max.
