ALED6000 Maximum ratings # Pin Description
A pull-down resistor to GND selects the 11 ILIM peak current limitation A PWM signal in this input pin implements the LED PWM current 12 DIM dimming. It is pulled-down by internal 2 µA current 13 LX Switching node 14 LX Switching node Connect an external capacitor (100 nF typ.) between BOOT and LX pins. The 15 BOOT gate charge required to drive the internal n-DMOS is recovered by an internal regulator during the off-time 16 GND Signal GND Exposed pad must be connected to -- E.P. 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.
