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

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
