PI FU CTIO S
VOUT (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 VCTRL is greater
than about 1.8V, full-scale LED current is generated. When
VCTRL is less than 1V, LED current is reduced.
VIN (Pin 5): Input Supply Pin. Must be locally bypassed
with a 1
µF X5R or X7R type ceramic capacitor.
SW (Pin 6): Switch Pin. Connect inductor here.
