Pin Description/Functions
AGND(pin A1): Analog ground pin. The analog ground pin
should tie directly to the GND pin.
V
with a capacitor, as close to the device as possible, connected
between the V
V
device. Connect the output capacitor between the V
GND pins as close as possible to the device.
V
switch devices. Keep the inductor connection close to this pin
to minimize EMI radiation.
GND(pin C3): Power ground pin. Tie directly to ground plane.

FB(pin B3): Output voltage feedback connection. Set the pri-
mary White LED network current with a resistor from the FB
pin to GND. Keep the current setting resistor close to the de-
vice and connected between the FB and GND pins.
NC(pin A3): No internal connection is made to this pin. The
maximum allowable voltage that can be applied to this pin is
7.5V.
SHDN(pin A2): Shutdown control pin. Disable the device with
a voltage less than 0.3V and enable the device with a voltage
greater than 1.1V. The white LED current can be controlled
using a PWM signal at this pin. There is an internal pull down
on the SHDN pin, the device is in a normally off state.
