OUT
(Pin 1):
Output Pin. Connect to output capacitor and
LEDs. Minimize trace between this pin and output capaci-
tor to reduce EMI.
GND (Pin 2):
Ground Pin. Connect directly to local ground
plane.
FB (Pin 3):
Feedback Pin. Reference voltage is 200mV.
Connect LEDs and a resistor at this pin. LED current is
determined by the resistance and CTRL pin voltage:

CTRL (Pin 4):
Dimming Control and Shutdown Pin. Ground
this pin to shut down the device. When V
CTRL
is greater
than about 1.8V, full-scale LED current is generated. When
V
CTRL
is less than 1V, LED current is reduced.
