NAME
Description
1
SW
Switching Pin. This is the collector of the internal NPN power
switch. Connect to inductor and diode. Minimize the metal
trace area connected to this pin to reduce EMI.
2
GND
Ground Pin. Connect directly to local ground plane.
3
FB
Feedback Pin. Reference voltage is 100mV. Connect LEDs
and a resistor at this pin. LED current is determined by the
resistance and CTRL voltage.
4
CTRL
Shutdown Pin and Dimming Control pin.
VCTRL > 1.8V generates full-scale LED current
VCTRL < 0.4V chip is off
Switching from 0.4V to 2.0V, PWM duty cycle controls the LED
current
5
VIN
Input Supply Pin. Bypass this pin with a capacitor as close to
the device as possible
