PIN FUNCTIONS
LED1 (Pin 1): Connection Point Between the Anode of the
Highest LED and the Sense Resistor. The LED current can
be programmed by:
I
mV
R
LED
SENSE

=
CTRL1 (Pin 2): Dimming and Shutdown Pin. Connect this
pin below 75mV to disable the white LED driver. As the
pin voltage is ramped from 0V to 1.5V, the LED current
ramps from 0 to (ILED1 = 200mV / RSENSE1).
GND1, 2 (Pins 3, 4): Ground. Tie directly to local ground
plane. GND1 and GND2 are connected internally.
CTRL2 (Pin 5): Dimming and Shutdown Pin. Connect it
below 75mV to disable the low noise boost converter.
As the pin voltage is ramped from 0V to 1.5V, the output
ramps up to the programmed output voltage.
FB2 (Pin 6): Feedback Pin. Reference voltage is 1.215V.
There is an internal 182kΩ resistor from FB2 to GND. To
achieve desired output voltage, choose RFB2 according to
the following formula:
