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

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
