Pin
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 200mV. 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.
A. VCTRL > 1.8V generates full-scale LED current
B. VCTRL < 0.4V chip is off
C. 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.
