Function
Analog ground.
Analog and Power supply input.
PMOS source connection for synchronous rectification.
Switch pin. Drain connections of both NMOS and PMOS power devices.
Power Ground.
Output voltage feedback connection.
Analog LED current control.
Shutdown control pin.
AGND (pin A1):
Analog ground pin. The analog ground pin
should tie directly to the GND pin.
V
IN
(pin B1):
Analog and Power supply pin. Bypass this pin
with a capacitor, as close to the device as possible, con-
nected between the V
IN
and GND pins.
V
OUT
(pin C1):
Source connection of internal PMOS power
device. Connect the output capacitor between the V
OUT
and
GND pins as close as possible to the device.
V
SW
(pin C2):
Drain connection of internal NMOS and PMOS
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
primary White LED network current with a resistor from the
FB pin to GND. Keep the current setting resistor close to the
device and connected between the FB and GND pins.
CNTRL (pin A3):
Analog control of LED current. A voltage
above 125 mV will begin to regulate the LED current. De-
creasing the voltage below 75 mV will turn off the LEDs.
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.
